Professional Software Inc. (617)444-5224 51 Fremont Street Needham, MA 021 94 Telex: 951579 We just made owning an Atari computer a lot more logical. Introducing the Rana 1000 disk drive. It!s a wliole new game for Atari computeis. This two digit LED readout displays a code that tells you everything you need to know. This switch tells you your write protect feature is keeping your information safe. The remaining switches provide readouts on density storage, error status, and drive number. This switch, when you touch it, tells you what track you're on. When Rana Systems introduced the Elite Series of Apple® compatible disk drives, we didn't know what a tremendous impact they would make. It turned out to be a line so outstanding in perfor- mance, styling, capacity, and price, that it instan- taneously made us a major force in the market. Well, needless to say, the response was so great that we were forced to create the same highly ad- vanced disk drive for Atari® A disk drive that when coupled with Atari's computer, could perform everything from accounting, financial planning, and stock charting, to word processing, business management, and letting you write your own pro- grams. Plus, we made it simple enough for a child to use, for learning anything from the alphabet to a foreign language. Woridng with a disltette versus plaiying with a cassette. Let's face it. The only reason Atari made a cassette option to their computer was to make it affordable. But now you don't have to settle for less. Because now you can get a diskette for your Atari computer which outperforms their cassette. With Atari's cassette you only get half the functions of a computer compared to what our floppy disk can give you. Their cassette is not only limited in the software available, but it also takes 20 times longer to get the information you need. And Rana's disk RanaSystems drive offers twice the storage capacity of either their cassette or disk drive. Why even stylewise our new low profile design not only looks 100 times more spectacular, but it occupies 3 times less space. And our new Rana 1000 also gives you a piece of its mind every time you use it, because our disk drive gives you informa- tion as well as takes it. And we think that says a lot. The disk drive tiiat has all the answers. Rana offers you a myriad of features Atari couldn't even conceive of. Like five electronic func- tions on the front panel that give you a LED read- out when touched. Our disk drive tells you what track you're on, and what density and how much information you're storing. And, we have a write protect feature which protects your diskette from being erased. In fact, no other disk drive can offer you that. As you can see, it was easy to build a disk drive superior to Atari's. Because for every reason you buy a disk drive, Rana has superior technology. The Rana 1000 disk drive. It brings your Atari computer to a higher level of sophistication for a price one third lower than Atari's. So your choice shouldn't even be a matter of logic. Just common sense. Always a step ahead. 21 300 Superior Street, Chatswofih. CA9t311 21 3- 709- 6484. For dealer intormation call toll Ireo 1.800-421-2207. In California only call: 1-800-262-1221.

ISSN EDITORS NOTES A recent article in Business Week touched on the topic of deceler- ating sales in the home computer market. Not that sales are de- clining, mind you; they're just not accelerating with the velocity that many had predicted. One of the recurring questions raised was the value of home computers aside from their use as game machines. If you process words, then obviously a word processing package is of use to you. Perhaps you need a data management program or even a home ac- counting package. Beyond these uses, what can you do? Or are these uses intrinsically enough? Our opinion is that there's a bit of a crisis of expectations involved, and perhaps an inch or two of gap between the reality of a basic system and the adver- tisements describing a fully con- figured system. It is, in fact, quite frustrating to discover that a home computer may cost you $99, but the memory expansion, disk drives, and so on to go with it - which turn it into a far more practical system - may cost you an additional $1,000. And that's before you buy that word proc- essor or data manager software. In most consumer market items there's far more parity of pricing, given that one rarely expects to pay more for a lens than a camera; more for a record than a player. In the home com- puter market, especially the low end, this pricing parity expecta- tion is even more greatly exag- gerated. There's not very much you can add to your computer that doesn't cost more than the computer did. We suggest that this simple mismatch may have a great deal to do with perceptions of machines such as the Timex/ Sinclair which has recently been falling off in sales. And these aren't sales that are necessarily being lost to other market leaders. The industry is simply not expanding at the rate many expected. Perhaps bundling (selling a combination of home computer, peripherals, and software) will provide an answer. We'll be closely watching the success of Adam, and an expected bundled Commodore 64 package, to see what the market decides. Random Bits: Where is Baby Blue? As all the industry specu- lates on the arrival of the IBM Home Computer (frequently called Peanut), other industry stocks are being buffeted by the rumors and speculation about this long-pending announce- ment. One important point to remember is that there are liter- ally thousands of computers being sold each day, and the market is truly growing. Commodore 1541 disk drives are in short supply, and a rumor exists for every possible reason. While some have sug- gested that a recall has quietly taken place, it appears to us that the shortage that Commodore predicted several months ago is actually upon us. This shortage has been complicated by an ap- parent high rate of problems with the drives, causing exces- sive downtime and consumer complaints. Editor In Chief 6 COMPUTf!

Tone Generator For The VIC I own a VIC-20 and I am very pleased with it. However, I would like to know if it's possible to add a tone generator so that when I hit a key on the keyboard a tone is heard to indicate that an entry was made. I've seen this on other computers and find it most useful. Kevin M. Regenhard The positive stroke keyboard tone generator you mention is not built into the VlC-20. However, it is possible to program this useful function into your VIC. Type in, SAVE, and then RUN the following short BASIC loader which will POKE in a machine language program. The program is written to run in the cassette buffer, so it shouldn't interfere luith your BASIC programming memory. Once the program is POKEd into memory, 5YS828 to start, and press RUN/ STOP - RESTORE to stop. 60000 FOR A=828 TO 861: READ B: POKE A,B: NEXT: END 60010 DATA169, 15, 141 , 14, 144, 120, 169, 78, 14 1,20,3,159,3,141,21,3,88,96 60015 DATA165, 197,201,128,240 60020 DATA?, 101, 197, 105, 128, 141, 12, 144, 76 ,191.234 The Atari Mystery Connection I took apart the Atari 400 and noticed on the back of the main board chip that there is a connection not in use. What is this connection for and why is it not in use? Ki Jeong Yun This connection, also found on the Atari 800, is used by Atari to test the machines on the assembly line. Due to its inaccessibility, it has never had any other use, although it could possibly be used for expansion. Double-Spaced Listings On Commodore Printers I have a Commodore 64 and a Commodore 1525E printer. There are many occasions while I'm de- bugging a new program when a double-spaced paper listing would provide a lot more room to make corrections and additions. Is there a way to force the LIST command to 10 COMPUTI! November 1983 double-space on the printer without modifying the program being listed? Perhaps Jim Butterfield could suggest a short machine language routine. Stephen D. Eitelman Yes, it is possible to command the printer to double-space during the LIST command, hi fact, all Commodore printers and many other printers have this ability. You will also, of course, see double-spaced listings on your screen. With any Cotnmodore printer, you can enter and run one of these short BASIC programs, which will POKE a machine language program into the cassette buffer to create double-spacing. 5 AD = PEEK(55)+PEEK(56)*256-20 10 I=AD 15 POKE 5 5, AD AND 255 : POKE 56, , AD/256 20 READ A: IF A=256 THEN END 25 IF A=- -1THENA= =(AD+11)AND255 26 IF A=- -2THENA= =(AD+ll)/256 30 POKE ] [,A:I=I+1:G0T0 20 35 PRINT' 'I CLR} RUN WITH : {RED }SYS' 'AD 40 CLR 828 1 DATA 169,-1, ,141,38,3 834 ■ DATA 169,-2, ,141,39,3 840 i DATA 96,201, ,13,208,5 846 i DATA 32,122, ,242,169,13 852 DATA 76,122, ,242,256 5 PRINT" {CLRlRUN WITH SYS 579" 10 1=679 20 READ A: IF A=256 THEN END 30 POKE I,A:I=I+l:GOTO 20 679 DATA 169,178,141,38,3,169,2 687 DATA 141,39,3,96,201,13,208 695 DATA 5,32,202,241,169,13,76 703 DATA 202,241,256 Tl Free Memory Techniques I would like to clarify and expand upon the ideas expressed by Howard Patlik in "More on TI Mem- ory" (Readers' Feedback, August 1983). This two- line program for determining free memory on the TI-99/4A was offered: 1 A=A+8 2 GOSUB 1 If you RUN this program alone and PRINT the variable A, you will find the amount of avail- able memory less the 37 bytes required by the program itself. {A equals 14536, so A plus 37 equals 14573 bytes of memory for programming.)

Each time this GOSUB executes, 8 bytes of memory are consumed and thus 1817 times 8 is 14536. As many as 7 bytes may still be unused. Of course, if this two-line routine is entered with a program already in memory (providing the variable A is not used within this program), you will find the amount of free memory less 37 bytes when you RUN and PRINT A. There are some more considerations. String variables and graphic characters defined above CHR${127) will require additional memory that this two-line routine will not pick up. The TI-99/4 has 256 more free bytes than the TI-99/4A, but if graphic characters above 127 are used, then both will use the same amount of memory. Screen and BASIC overhead is 1792 bytes. And if all or only the graphics character 159 is used, then overhead is 2048 bytes {1792 + 8*{159- 127)). The 16KT1-99/4A is, of course, actually 16,384 bytes. So, 16,384 minus 1792 is 14,592 bytes free. (There is a slight discrepancy from the two- line method of up to 19 bytes.) Here is another way to find memory size using CALL PEEK. For TI BASIC, you need the Mini Memory or the Editor/Assembler cartridges. Type in CALL PEEK{-31974,A,B). Again the vari- ables A and B should not be in the program. Then PRINT A*256-l-B-1776. With no program present, this will give a size of 14577 bytes free. To check this with TI Extended BASIC (Ver- sion 110), type PRINT A*256-(-B-2455. The TI's response is 13886. Now type SIZE. The TI re- sponds with 13886 BYTES FREE. Another user of memory in TI BASIC is Ter- minal Emulator II. It takes about 512 bytes. It is also well-known that the disk controller uses con- sole memory. Even after ENTERing CALL FILES(l) and the NEW command, it still uses 1052 bytes. Here's how to free up this memory. Type CALL LOAD(-31888,63,255) and NEW. Again, in TI BASIC the Mini Memory or Editor/Assembler cartridge is needed, but in TI Extended BASIC, the 32K Expansion is needed. To restore disk drive(s) and disk controller, use the command BYE or FCTN QUIT. Paul E. Schippnick Atari Upgrade Update We have recently heard from several jactory authorized Atari service center representatives who tell us that there is an inexpensive (under $30) upgrade for the lOK ROM operating system. The original operating system of the 4001800 had a number of minor errors (bugs), and the Revision B operating system corrected these problems. This is the first time to our knowledge that Atari has offered this upgrade. To check which operating M COMPUTE! November 19B3 system you have, enter: PRINT PEEK(58383). If you get a 56, you may want to visit your nearest service center and get the upgrade (a value ofO returned means you already have Revision B). Anottier Perfect Commodore INPUT In the last several issues I have seen a number of "Perfect INPUTS" to avoid Commodore's return to READY from input. All of these methods work. In my opinion, however, since you can continue from READY by entering CONT on a clear line, their disadvantages outweigh their advantages. I have another way of avoiding this problem. It uses the standard INPUT statement and CBM's active screen. When an input statement is ex- ecuted, CBM BASIC prints a ? at the current cursor position, then moves the cursor to the right one additional space. All of the positions to the right of the cursor are automatically allocated for inputting data (up to 80 characters). By printing some default value into this area before executing the input statement, not only do you avoid the return to READY, but you also allow for inputting default values by just hitting RETURN. For example: 10 VA = 10 : REM SET DEFAULT VALUE TO 0 20 PRINT "WHAT IS THE NEW VALUE": PRINT " "; VAf"{UP}" 30 INPUT VA 40 PRINT "THE CURRENT VALUE IS"; VA 50 INPUT "IS THE VALUE CORRECT (Y/N) [3 SPACES 1y{ 3 LEFT]"; A$ 60 PRINT "WHAT IS THE VALUE"; TAB(20);"D EFAULT VALUE" 70 PRINT TAB(18)r"fUPJ"; 80 INPUT DV$ This appears on the screen as: WHAT IS THE NEW VALUE ?10 THE CURRENT VALUE IS 10 IS THE VALUE CORRECT [Y/NI ? Y WHAT IS THE VALUE ? DEFAULT VALUE The flashing cursor is positioned over the 1, Y, and D respectively. By hitting only the RETURN key (3 times), you INPUT 10 to VA, Y to A$, and DEFAULT VALUE to DV$. If you want some other value, you need only type it in before hitting RETURN. By taking a little time in choosing default values when writing a program, you can save a lot of time when running it and entering data. Dennis D.

Could you tell me what this POKE is? Also, how do 1 make my taped programs run after being LOADed without my intervention? Tim S. Hallen There are a munber of ways that you can place the VIC- 20 or the Commodore 64 into the upperllowercase or "text" mode. Using a POKE, the locations are 36869 on the VIC, and 53272 on the 64. These locations are on the VIC (Video Interface Chip) chip of each machine, and tell the computer where to get its character set. On the VIC, the normal value is 240, and on the 64 it's 21. To place the VIC into the text mode, POKE 36869,242 and for the 64, POKE 53272,23. To return to uppercase/ full graphics (normal) mode, POKE 36869,240 on the VIC, and POKE 53272,21 on the 64. There are other methods ivhich switch between text and normal modes. One of these is to hold doivn the COMMODORE and SHIFT keys. To sivitch to text mode, press and continue to hold the COMMODORE key while pressing the SHIFT key. To return to normal, simply toggle the keys again. Another method, and probably the safest and most efficient, is via the PRINT command. To switch to text mode, txjpe PRINT CHR$(14) then press RETURN. To return to normal mode, type PRINT CHR$(142). These PRINT state- ments can also be used within a program if you wish. There are a number of ways to make the computer automatically run your programs after LOADing. The easiest is via the keys on the keyboard. After positioning your tape cassette to the beginning of the program you wish to LOAD and RUN, press and continue to hold the SHIFT key, then press the RUN/STOP key. This will LOAD your program into memory, then run it 16 COMPUTE! November 1983 without your having to type and enter RUN. Another method is to "string load" your cassette programs. Sthrig LOADing programs is LOADing and RUNning one program which in turn LOADs and RUNs the next program on the cassette tape. To accom- plish this, LOAD aiid RUN your first program nor- mally, and use the last statement of this program to call in the second program with a LOAD command. For instance, the last line of the program would read: 60000 LOAD "filename". Wheti the program encounters this statement, it will automatically LOAD and RUN the next program on the cassette tape. This can also be a very useful programming technique for saving memory if, for example, you have a program that has a long list of instructions for the user to read before running the program. You can use the first program in the "string" to display the instructions and then load in the second program when the user is finished reading. Use Any Tape Recorder With Atari? I am a new owner of an Atari 800. 1 eventually plan to purchase a disk drive, but as a temporary storage device, I would like to use my Panasonic cassette recorder, rather than purchase an Atari 410 or 1010 program recorder. Is this possible? If so, how do I go about wiring connections without causing any damage to the computer? Mark Inman The serial plug used to connect Atari peripherals has connections for audio out and audio in. You can attach a standard recorder to audio out and record CSAVEs, but there is no way to get the computer to read the audio- in line (which is used to play the audio track through the TV speaker). The Atari 410 recorder has a special analog to digital circuit used to translate tape tones into digital information that the computer can read. Text On The Apple High-Resolution Screen My family has just purchased an Apple II + computer. I can program graphics on the high- resolution screen, but things just aren't the same without text somewhere besides the text window at the bottom of the screen. Is it possible to put text on the high-resolution graphics screen? Mark Hayek You can put shapes that look like text on the Apple's high-resolution graphics screen by using the program "HRCG" (high-resolution character generator) that comes on the DOS Tool Kit disk. This program can be accessed from a BASIC program and will load shape tables representing different character sets into memory just below DOS. Normally, these shape tables will produce the stand- ard ASCII characters on the high-resolution screen. However, there are other character sets on the Tool Kit Have \bu Read The Reviews On Our New AtariWriter? Atari's New Word Processor. Try it, be your owti aitic.

Programming The Commodore Joystick I own a Commodore VIC-20. 1 have learned how to program games, but I have not learned how to program the games to respond to a joystick. I have looked in the VlC-20 Programmer's Reference Guide, but I did not understand the in- formation. 1 would like to know how to program games to respond to a joystick. Would you please explain this to me? Mitchell Kerman In both the VIC-20 and the Commodore 64, the joystick is.programmed by PEEKing two bytes. The VIC is designed to handle only one joystick, and it takes two bytes to control that joystick. In the VIC, location 37137 is PEEKed to read the joystick for the up, down, left, and fire button movements. Location 37152 is PEEKed to detect movements to the right. The 64 is designed to handle two joysticks, and unlike the VIC, each joystick is controlled ivith one byte. To detect the position of a joystick plugged into port A, PEEK 56320, and for port B, PEEK 56321 is used. To see just how easy it is to detect movement on the joystick, plug in your joystick, type in one of the following short programs, and then R UN. The programs simply PEEK the joystick control bytes, and then PRINT that reading to the screen. For the VIC-20: 10 PRINT PEEK(37137),PEEK(37152); GOTO 10 For the Commodore 64: 10 PRINT PEEK(56320),PEEK(56321): GOTO 10 As you run the programs and play with the joystick, you'll see the values printed to the screen change as the values in the joystick ports change. You can program the joystick into your games by PEEKing these locations, arid using IF. . . THEN statements in your program to process the information . A quick word about programming techniques here. Because the joystick control bytes are often shared (that is, they do other things besides read the joysticks), it is more efficient to PEEK only the affected bits in the joystick control bytes. This will filter out other informa- tion not connected to the joystick. This is done by AND- ing your PEEKs. For more information on which bit is used for each joystick application, consult the Pro- grammer's Refeference Guide for your specific computer. 20 COMPUTCJ November 1983 Saving Macliine Language Programs I'd like to protect programs I write on my VIC-20, and I know that using machine language accom- plishes this. But how do you save machine lan- guage on tape? Dave Karlson The easiest, quickest, and most efficient way to save a machine language program is from within a machine language monitor. There are many monitor/assembler packages available for your VIC-20, among them "TINYMONl," published in COMPUTEI's First Book Of VIC, and the VICMON Machine Language Monitor Cartridge available at your local Commodore dealer. The folloioi)ig technique will also work success- fully on the Commodore 64. Once a monitor is loaded and running, the usual format for saving to cassette tape is: S "name", XXXX, y yyv, Ol where S = save, name = name of program, XXXX = starting address of the machine language program to be saved, YYYY = ending address of the program, and 01 is the device number (tape). Saving to disk would use the same format, except that the device number would be 08 (disk). However, it should be noted that some monitor/assemblers use a different format. See the accompanying documentation. There is another way to save machine language programs, but it involves some redefining of the VIC's operating system. You can save a machine language program in the same manner that you would a BASIC program. To accomplish this, you have to redefine, or POKE three sets of pointers. First, you have to determine the beginning and the ending addresses of the machine language program. Once this is known, POKE 43 and 44 (start of BASIC pointer) to point to the beginnijig of the program, POKE 45 and 46 (start of BASIC variables, or end of BASIC pointer) to point about 10 bytes past the end of the program, arid POKE 55 and 56 (highest address used by BASIC) to pwint about 30 bytes past the end of the program. Next type CLR. Nozv you are ready to save to tape or disk in the normal manner, i.e., "SAVE filename, 1" (for tape) or "SAVE filename, 8" (disk). To LOAD the programs back into memory, use the standard format for LOADing machine language pro- grams: LOAD filename, device number, 1. For example, LOAD "filename", 8,1.

Features Editor Are you thinking about buying a computer for the first time, hut don't know anything about computers? Or maybe you just purcltased a computer and are still a bit baffled. Each month, COMPUTE! will tackle the questions most often asked by beginners. Ql have recently purchased a computer with a cassette recorder. In a recent issue of COMPUTE!, an author stated, "Remember that the safest way to make sure that your program is not lost forever is to save it at least every half an hour that you work on it." Does this mean that, when typing in the extra long programs, you should stop half an hour into the program and save it, then continue typing from that point on? A To be safe, yes. You might want to stop and save the program even more often, or less often - depending upon how much of your work you are willing to reconstruct in the event of a disaster. Remember that programs loaded from disk or tape, or typed on the keyboard, are kept by the computer in Random Access Memory (RAM). RAM holds this information only while the com- puter's power is on. If you are typing in a long program and a thunderstorm suddenly knocks out the electricity, or if someone kicks loose the power cord, all your work will be lost. You would have to start over again from the beginning. That's why most people "safety save" the program they are typing or writing. Admittedly, if you are working with a cassette recorder instead of a disk drive, this can be inconvenient because of the waiting involved. A very long program might take ten minutes to save. If you save your work every half-hour, you could spend one-third of your time waiting for the recorder. A good compromise might be to save to tape once every hour. Decide for yourself: If there are no storms brewing, if the power cords are safely hidden from passing feet and pets, and if no one else is around to accidentally turn off your com- puter, you can probably get away with saving your work less often than someone who must put up with such hazards. QI own an Atari 800 (48K) with a 410 Program Recorder and my brother owns an Atari 400 (16K) and a 410 also. Is there any way to interface 22 COMPOTS! November 1983 the two computers in order to play a program through both at the same time? Alt is possible to hook up two (or more) com- puters to share a program - even two com- puters which are normally incompatible -but there are several complications involved. First, you would have to buy or make a cable to hook the two computers together. One way would be to use the parallel or serial ports on a pair of 850 Interface Modules, or the built-in serial bus on each computer (although the latter method would interfere with access to peripherals, such as your cassette recorders). I know of no cables for this purpose, and making one would be a task for a knowledgeable technician. Perhaps using a pair of modems would be the easiest way to hook up the computers. Each computer would require its own modem and tele- phone. You would call up your brother's computer and link them together over the phone lines. Of course, this would also require the proper terminal software - a program to allow each computer to act as a remote terminal, communicating with the other. Whatever you typed on your computer would appear on your brother's screen, and vice versa. In effect, you would be "sharing" a program on both computers - the terminal program. But to do anything more would require a special program to take the place of the terminal software. You don't mention in your letter what type of program you want to share on both com- puters. There are only a few programs designed for this. If you want to play an interactive game - with you and your brother making moves and countermoves from your own computers - you'd need a game program specially designed for this. The only one I've heard of is Commbat by Adven- ture International. This is an interactive tank battle game with simple graphics that can be played over the phone lines between even normally in- compatible computers, such as a Radio Shack TRS-80 and an Atari. Be aware, however, that such games are lim- ited by the speed of data transmission over the phone lines. It is very difficult to program fast action and flashy graphics.

And your Atari ' home computer just became more fun than ever. Because River Raid and Kaboom! have been re-designed to take full advantage of home com- puter capabilities. Far beyond anything you've ever experienced before in video games. Unique gi*aphics, crisp detail and brilliant sound all come together with spectacular impact. River Raid,™ the battle adventure up the "River of No Return." The realism of Cai'ol Shaw's River Raid is utterly amazing. It challenges your reflexes, stamina and sti"ategic savvy as you battle your way up tiie winding river Enemy choppers. Jets. Tanks. Hot-air balloons. Ships. All out to blow you to smithereens. But you strike back. Keeping one eye on the ever- changing teirain. Bridges. Mountains. Canyon walls. Islands. One false move and it's curtains. And if you're up to it, now you can skip easier sections of the river and get right to the heart of tlie battle. Everything that made River Raid such a smashing hit is here. And tons more. Kaboom! ', the award- winning game of catch with buckets and bombs. Larr>^ Kaplan's Mad Bomber is back. The buckets are back. But now, in Paul Willson's adaptation, you can drop the bombs, while someone else tries to catch them. Imagine dropping bombs. Faster and faster. T) the ever- quickening pace of the 1812 Overture. You shift right. Left. Back again. All the way right. He misses! You win! Now it's your turn to catch. The pressure mounts. The bombs start flying. You dash to catch them. And so it goes on into the niglit. And eveiytime you hit a new high score, it's displayed after the game, just like at ttie arcade. Kaboom! and River Raid for your Atari home computer. They're here.

There are two types of modems commonly used with personal computers. Acoustic moderns have a set of soft rubber cups into which you insert the phone's handset. One cup contains a speaker, which generates audio tones, the other a micro- phone, which receives tones from the other modem. Once you have the correct hardware and software for telecommunications, there is a great deal of information that you can access. Direct-connect modems plug directly into the telephone through a modular phone jack. Some, like the VICmodem, are cartridges that are plugged directly into a port on the computer. Others are stand-alone units about the size and shape of an eight-track cartridge tape which can be placed directly beneath the phone and plugged in. Some of these have a feature which allows you to switch from phone functions to modem func- tions. This spares you from having to keep con- necting and disconnecting the modem when you want to use the phone to make a call. Acoustic modems are generally less expensive but direct-connect modems gen- erally offer a better connection, since the sound frequencies nec- essary for telecommunications are generated directly on the phone lines. Extraneous room noises can interfere when you're using an acoustic modem if the phone handset is not sealed very tightly in the cups. Some computers come with a built-in modem. The Radio Shack TRS-80 Model 100 Portable Computer is an example. The modem functions and terminal software are contained inside the computer; all you need is a cable to start telecomputing. Dumb Peripherals If you turn your personal com- puter into a terminal when using a modem, how can it accomplish something as complicated as transmitting data to another terminal around the block or around the world? Your computer must be able to send and interpret bits in the pattern you want, or you'll just be sending and receiving nonsense. This is why you need special software for telecommunications. Some terminal software comes on cassette, some on disk, and some in cartridge form. There are several terminal programs in this issue. Matching Up Also, a modem must be properly aligned with another modem before information transmission is possible. Both modems must be matched in several ways. Baud rate is the number of bits being sent every second. This can vary from 110, which is what the old teletypes use, up to 9600. The faster the rate, the lower your phone bills. But sending informa- tion as fast as 9600 bits per second really tests the capabilities of the telephone system. In order to establish communications, you need to know the baud rate at which the system you are calling is operating so that you can set your terminal soft- ware to the same rate. Another factor is rfi/;7/t'.\7»__^. Full-duplex means being able to send and receive data at the same time. Half-duplex allows for only one-way com- munication. If this is not matched correctly to the system with which you are communicating, you may see double characters on your screen or none at all. Some terminal software allows you to upload and download programs. Say you have a friend in another part of the country who just programmed The Racal-Vadic VA3413 is an acoustic modem. The telephone handsel is pushed into the soft rubber cups on the side. 28 COMPUTi!

Shopping by mail is possible through the Burbank-based "Fan- tasy Plaza." Expect to see more services like this spnngmg up. Computer programs over the radio. It is possible to download computer programs from your radio. The Microperipheral Corporation has even de- veloped a modem designed for reception of com- puter data from commercial radio stations. Though this is not a widespread use right now, radio stations and cable operations around the country may soon be following the lead of stations like KMPS in Seattle, which has been downloading computer programs by radio since March. A Buyer's Guide To Modems The following chart lists features of several modems compatible. with personal com- puters. We have tried to include as many as possible; any omissions do not represent an editorial judgment on their quality. If you need more information about a specific modem, consult the list of manufacturers and distributors. Here is a brief explanation of the categories on the chart: • Compatibility. This is probably the most important consideration in choosing a modem. Since modems are serial devices, most are RS-232 compatible; some, however, are specific to certain machines. Even if your computer has an RS-232 port, make sure you have the necessary interface cable. • Communication Standard. The Bell 103 is the most common communication standard found on modems available for personal computers. It allows information to be sent at the rate of 300 baud; some can go as fast as 600 baud. The Bell 202 and 212A facilitate data transmission at a faster rate. • Coupling Method. A modem can link your home computer to the phone lines in one of two ways. A direct-connect modem plugs directly into the phone through a modular phone jack. Acoustic modems re- quire a standard desk phone handset, so that the handset can be pushed directly into the modem's soft rubber cups. • Baud Rate. Or, more technically correct, bits per second. A speed of 300 baud is pretty standard on most of the modems you will encounter. • Duplexing. Half-duplex and full-duplex indicate whether information can be sent and received at the same time. When tele- computing, failure to match your modem's duplexing abilities with those of the modem at the other end may result in character dupli- cation or "echo." • Auto-Anszoer. This feature is necessary if you want to be able to automatically answer calls from other telecomputing stations (for example, if you want to set up a bulletin board system for others to call). • Auto-Originate. Lets your modem dial phone numbers to call other telecommunica- tions facilities. • Self'Test. Some modems have the capability to test themselves to see if every- thing is hooked up correctly and working, • Carrier Detection Indicator. How can you tell if you have connected with the party at the other end? Most modems have a way of indicating this to you, either by a light or LED on the modem itself, or by a signal that appears on the screen. • Power Supply. Your modem must oper- ate from some kind of power source. Usually this is through a wall socket or internal bat- tery; sometimes the modem draws its power directly from the host computer. • Cables/Connectors Included? Connecting your modem to your computer may require the purchase of additional cables or con- nectors like an RS-232 cable (if you do not already own one), or some other kind of system-specific connector. Some, like the VICmodem, plug directly into the computer. • Terminal Softiuare Included? Some modem packages include terminal software. If the one you buy does not, you will need to either purchase a program or type one in from a magazine or book, • Price. The modems listed on this chart include suggested retail prices at the time of this writing. 32 COMPUni November 1983 Buy Miaomodem lie™ with Smartcom Fsoftware ri^tnow and get this $140 value FREE!

What brand should you buy? What "extras" are needed? Will you need software just to operate your peripheral? This article helps define the more critical issues involved. Computer enthusiasts often brag about their "sys- tems," adding an aura of sophistication to their home setups. These systems usually consist of a basic microcomputer surrounded by an assort- ment oi peripherals. Essentially, a peripheral is anything you plug into your computer. Without even realizing it, you started adding peripherals and building your system as soon as you bought your computer. Your first peripheral was most likely a TV or video monitor, and the next was probably a cassette tape unit to load and store programs or a joystick to use with your fa- vorite game. From there, the list of possible peripheral devices goes on and on; printers, disk drives, modems, memory expansion cartridges, light pens, speech synthesizers, plotters, etc. It's up to you to decide which peripherals you need: a disk drive for serious word processing, a color monitor for really sharp video displays, a modem for telecommunications. The economics of the situation should dictate the amount of time you spend comparing the available models of the item you want. If you have been shopping for any of these items, one thing you've realized, is that it's not at all unusual for a peripheral device to cost quite a bit more than the computer to which it is attached. It might take you a while to get adjusted to the idea of hooking a $600 printer up to your $100 computer. But the overriding issue is compatibil- ity: Will the peripheral you want work with your computer system? It's easy to see that you should choose your peripherals carefully. 40 COMPUTE! November 1983 Which Brand Is Best? The obvious way to guarantee that the peripheral devices you buy will work in your system is to buy them from the same company that made your computer. Another source is the alternate "third party" suppliers and many of them offer truly innovative designs. Most home computer peripherals are some- one else's product wearing a new name. The com- puter company buys the hardware in huge quan- tities from the original manufacturer and then puts on its own brand label. In many cases, a simi- lar product is also available directly from the orig- inal maker. The key to whether a product is a better buy from the original manufacturer or the reseller can lie in whether the reseller just slapped on a logo or whether the product was modified to optimize its performance in conjunction with a particular computer. This isn't usually something that is obvious. One way to check is to see if the pe- ripheral supports any of the computer's special features. For example. Commodore computers have a set of built-in graphics characters which are directly accessible from the keyboard. Com- modore sells a printer made by another company, but modified to print the special characters. Similar printers are available under other brand names,. but the others either will not print the graphics characters or will print them only if you pay extra for an additional ROM chip and install the chip in your printer. Read The Fine Print Price should not be your sole concern when de- ciding what peripheral to buy. An important factor to consider is ease of interfacing. Again using printers as an example, a $300 printer that requires a $75 interface module to be used with your system is not a better buy than a $350 model that would plug in directly. Moreover, all interfaces are not ♦ Popular Computing. No\ ember, 19H2 fAppltSuftalk. April 1982 Everyone's talking about The Home Accountant.

We recently saw an interface which could be used to connect the VIC-20 to a popular brand of dot matrix printer. We assumed at first that using the interface was simply a matter of plugging one cable from the interface into the computer and another cable into the printer. It was only when we read the fine print in the instruction manual that we discovered we had to go inside the printer and solder in a wire to provide power for the in- terface. Such a modification would certainly void any warranty on the printer, and should not be undertaken thoughtlessly. This is the kind of detail that you need to investigate thoroughly before you buy any peripheral that doesn't plug directly into your system. You should also check to see if any special cables are required to connect the peripheral to your computer or to the necessary interface. Many buyers have been dismayed to arrive home with a new peripheral only to discover that a special cable is required to hook it up to their system. They can get even more dismayed when they discover that the manufacturer wants $35 for the necessary cable. Owners with some soldering experience may be able to save some money by building the cable themselves if they can find the necessary connectors, but, again, it's really not a job for beginners so you should make sure that all necessary cables are included with the peripheral. The Software Issue Yet another item to consider is support software. Some peripherals require no special software; others are useless without it. For example, the same light pen can be used interchangeably on an Atari, VIC, or 64. However, without software to read the light pen and convert the value for the light pen position to an equivalent screen location for your particular machine, the pen doesn't do you much good. If you're not a sufficiently advanced pro- grammer to write your own support software, you should be sure that programs for your com- puter model are included with the hardware. This is especially true for complex peripherals like speech synthesizers and plotters. If you don't get software for your computer with the device, you can face possibly spending quite a bit of time de- veloping your own. Lack Of Standardization There are few standards for home computer peripherals. Much of the lack of standardization is the result of the various companies following dif- ferent design philosophies. For example, the mechanical workings of all 5-1/4 inch floppy disk drives are essentially identical, but drive units for particular computers are not at all interchangeable. 44 COMPUTE! November 1983 Using the same basic hardware, a Commodore drive stores data on the diskette in 683 256-byte sectors; a TRS-80 Color Computer drive creates 630 256-byte sectors; an Apple II drive, 560 256-byte sectors; and a Texas Instruments drive, 360 256- byte sectors. An Atari drive uses 720 sectors, but each sector is only 128 bytes long. The Commodore writes the directory on track 18 of the disk, the Apple and TRS-80 on track 17, and the TI on track 0. This not only makes the disk drives incompat- ible, but also means that disks written by one brand cannot be read by another. Each manufac- turer has strong arguments why the particular method it chose is the best, and no one seems wil- ling to compromise in the name of compatibility. Interfaces A few attempts at standardization have been made. For example, a company called Centronics was one of the first major suppliers of computer printers, Centronics used a parallel interface scheme in which data was sent to the printer one byte at a time. Companies which entered the mar- ket later used Centronics' connection so that their printers could be easily attached to computers set up for Centronics printers. So this connection scheme, with its 36-pin plug, became the de facto standard, and Centronics parallel interfaces are now available for most home computers. A more formal standard has been established for serial data communications. The standard, called RS-232, calls for a set of wires including a transmitted data line, a received data line, and a collection of "handshaking" signal lines to regu- late data transfer. Moreover, a particular type of plug called a DB25 is almost always used on RS-232 data lines, and each pin on this plug has been assigned a particular RS-232 signal. So if you have an RS-232 port on your computer, you can interface without problems to an RS-232 peripheral, right? Unfortunately, it's not always that simple. The RS-232 standard defines a set of signal lines, but fails to specify what shall be considered a valid signal on those lines. Some RS-232 systems use + 12 volts and -12 volts as the two signal levels, some use -I- 5 volts and -5 volts, and a few others use -1-5 and 0 volts. For example, the VIC-20 and Commodore 64 have the ROM software built in to support RS-232 communications through the user port on the computer, but you still must plug an interface module into the user port to increase the output voltage levels before you can use most non-Commodore RS-232 devices. You should be aware of this before purchasing any RS-232 "standard" equipment. At some point in the future, one company may come to so dominate a sufficiently large share of the home computer market that it determines the standard for everyone.

This is a frequently asked question nowadays, and a good answer can be hard to get. Low-priced microcomputers are designed with the idea that you'll use the TV that you already have, to keep costs down. But perhaps you don't want to inter- rupt the whole family's TV viewing every time you want to work on a program, or perhaps there was no TV set in your home before you got a computer. In these cases, you must shop for a TV ~ and some TV sets are much more suitable for computer use than others. Size And Color The first question to be settled is, what size? That depends on whether you want to look at the screen from across the room, with the computer on the coffee table in front of you, or wnether you want to put the TV on your desk right behind the keyboard. The coffee- table arrangement is usual for joystick game playing, and the ideal TV size is the same as for watching TV programs at the same dis- tance. But a TV set that is to go on your desk should probably be in the 10- to 12-inch range; a 19-inch will be far too big to read comforta- bly, and even a 5-inch will give a crisp, small, very readable display, with letters about the same size as those produced by a pica type- writer. Color or black-and-white? That depends mainly on how much money you want to spend and whether you want a color picture. For computerizing your finances or learning BASIC, you probably don't need a color dis- play; for playing Pac-Man, you probably do. Very small (under-lO-inch) color TV sets often show a lack of fine detail because the color phosphor dots can't be made small enough in proportion to the size of the screen; no such problem occurs with black and white. A computer that generates a color dis- play can of course be used with a black-and- white TV; you get a black-and-white version of the display, with different colors rendered as different shades of gray. A few computers, such as the Timex/Sinclair 1000, do not gen- erate color. The main thing you want out of the TV set's performance is sharpness, in the deal- er's showroom, watch TV programs and commercials that place lots of lettering on the screen. Maiiipulate the fine tuning until the lettering is as sharp as possible, then look at the Final results. An overall smeared appearance is a bad sign; the better you can get the lettering to look, the better the TV set will perform with a computer. Convenient Controls You also need convenient access to certain controls - volume, brightness, contrast, and, for color sets, tint and color saturation. All of these controls need readjusting when you switch between computer usage and ordinary TV viewing; they should be conveniently accessible on the front panel, not hidden away in back. Preferably, the TV set should also have some other controls for occasional touching up: width and horizontal linearity adjust- ments can keep you from losing part of the display at the edges, and focus and video peaking adjustments can give you a sharper picture. These latter adjustments need touch- ing up only rarely, so it's fine if they're on the back panel or inside. Not all TV sets have them; check a circuit diagram to be certain. If you come across a TV with direct video and sound inputs for a video player, so much the better. You can connect your computer to them - contact the manufacturer to find out how - and get a sharper picture because the signal does not have to go through a mod- ulator or the TV set's tuner. In fact, if you aren't interested in watching TV programs, perhaps you should buy a monitor -a device like a TV set without a tuner or channel selec- tor, only a direct video input. If your computer uses sound, make sure that the monitor has sound capability. The ones intended for use with video recorders generally do, while monitors designed for use with computers often do not. Also, there are two types of color computer monitors. Get one with a composite video input, rather than RGB direct drive, unless you are sure that the latter is what your computer requires. 46 COMPUTII November 1983 When it comes to superior performance, we study our lines very careMy. Superior printer performance is not a fluka It evolves from analyzing printed line after printed line. Taking the time to test and retest. After 30 years of manufacturing precision parts, we know that there are no shortcuts. And so we took the Gemini-lOX and method- ically put it through its 120 cps pace. We achieved a print head life of over 100 million characters with an extremely precise dot align- ment creating each crisp character. So far so good. Next, sophisticated performance de- manded versatility. A wride choice of character sets, a buffer expandable || to 8K, and the ability to interface with all popular personal computers. We added macro instruction, giving Gemini-lOX the capability to perform up to 16 operations with one com- mand. We included as standard a paper feed system that has a friction and fully adjust- able tractor feed. Then we even built in the dexterity to print graphics and text on the same line. Dona And, of course, staying the best means constant reviewing and fine-tuning.

Publications Jnc® One of the ABC Publishina ComDonies ^^^ Guest Commentary The High Cost Of Personal Telecommunications Robert Braver As Iclecomnnmkalion becomes an increasingly impor- tant aspect of home couiptiting, the telephone rates and hookup fees are of interest to both the consumer and the telephone companies. Robert Braver, President of the Oklahoma Modem Users Group, raises some important issues ill this guest coiinnentary. Wc contacted South- western Bell of Oklahoma, and the remarks of their spokesperson are included. Sometime in mid-May, 1983, I called my local Bell business office to request that a trace be placed on my bulletin board system's phone line. Sonieone had been calling up my system and tying it up for an hour at a time by sitting at the prompt which asks for a user ID number. When requesting a trace, vou niust describe the type of calls you have been receiving. 1 thought that since these calls were not voice messages, there would more than likely be confusion when 1 tried to explain things to the business office representative. I expected to need about half an hour to explain exactly what a modem and bulletin board system is. After all, I had to do that when 1 first had the phone line installed a year ago. There Must Be Some Mistake To my surprise, she seemed to know all about modems. In fact, she informed me that since I used a modem on my phone line, I would have to pay a higher monthly phone rate. Of course, I thought she must be mistaken. Perhaps she was referring to the "Data Perfect" lines, which are used for high-speed (2400 baud) transmissions. I didn't need a special line for my relatively slow 300 baud modem. Even 1200 baud modems do fine on ordinary phone hnes. After about two weeks of arguing with Bell business office representatives, insisting that there must be some mistake, I received a copy of a tariff sheet from the Oklahoma Corporation Commis- sion. Bell was right. Their tariffs do call for the charging of a higher rate for connecting a computer using a modem to the phone lines. This section of Southwestern Bell's Oklahoma tariffs, called Information Terminal Service tariffs, was written in the mid-sixties. Obviously, this was long before there were home computers. When the tariffs were written, generally the only modem users were large corporations transmitting data 24 hours a day. Therefore, the rates for having a computer or similar device connected to the phone lines with a modem were somewhat higher. Because there were no home computers when the tariffs were written. Bell had no reason to distinguish between commercial and residential modem use. And now, almost 20 years later. Southwestern Bell is using those tariffs to charge personal computer users fi'oe times their normal phone rate if they wish to use modems with their personal computers. An Organized Response Since this tariff would seriously inhibit home modem use in Oklahoma, I immediately organized the Oklahoma Modem Users Group, or OMUG, to challenge Southwestern Bell and its unfair tariff. OMUG's main goal is to organize the modem users of Oklahoma and to undertake whatever legal proceedings are deemed necessary to force Bell to exempt home modem users from the Pro- visions of Information Terminal Service tariffs. As of this writing, legal proceedings are still in the future. OMUG has recently been raising funds and attempting to gain the support of home computer and modem manufacturers. OMUG has also been publicizing the situation to make sure that all modem users nationwide as well as NovemboM9e3 COMPUTE! 49 WEIMUASHTM POWHtnilGRAP ^X E VrORlD^ MOST mCSIKHNOliOGl You'll never see Infocom s graphics on any computer screen.

Not Limited To Olclahoma This situation, it turns out, may not be unique to Oklahoma, There are similar outdated tariffs in other states. And many experts in the industry seem to think that if Southwestern Bell is justified in charging higher rates to modem users in Ok- lahoma, it is just a matter of time before other states adopt similar tariffs or start enforcing their present tariffs (also written in the sixties). According to the tariff, anyone connecting "customer-provided data transmitting and re- ceiving equipment that processes data and/or performs calculations" including computers, as- sociated buffering devices, and/or concentrating devices with store and forward capabilities would all be subject to the higher rate. Although dumb terminals do not fall under the tariff, computers emulating dumb terminals do. And anyway, most terminal software packages have memory buffers, auto-logon capabilities, and other features. Fur- thermore, most so-called dumb terminals on the market today have memor\' buffers and micro- processors, which cause them to also fall under the tariff. Information Terminal Service is considered a business service. Therefore, as of July 11, 1983 {when Bell raised my rate), if I have a problem with the modem line, I don't call the residential division, but the business division of the Bell busi- ness office. As a "business," I ani entitled to a free yellow pages listing in the telephone direc- tory. But since I do not run a business, and having the ad might hamper chances of obtaining a court order to restore my old rate, I declined the free listing. But even without the yellow pages listing, I was told by the manager of the Bell business office that once a line is classified as a business, it cannot be restored to residential status. I would have to have the line disconnected, and pay $80 to have a new number installed. Is The Phone Company Justified? Bell seems to think that its tariff is perfectly jus- tified. Southwestern Bell's Rate and Separations Division Manager Charles Sutter spoke to a group of 40 home computer owners here in Ok- lahoma City in response to the outrage over the tariff. He was asked how Bell could justify charging a personal computer owner who uses CompuServe once a week the same rate as a large corporation transmitting data 24 hours a day. Sutter replied, "Well, I don't know how much you use your modem." There is no physical justification for an addi- tional charge for modems. Modems operating at speeds of up to 1200 baud do not require special 52 COMPirre! November 1983 lines. The four frequencies that 300 baud modems use are among the frequencies in human speech, and easily fall between the 300-3000 Hz bandwidth of an ordinary telephone line. And for most modem users, on-line time doesn't increase phone usage any more than having a teenager does. But Bell persists in charging the higher rate. Although representatives claim that Bell is not actively pursuing computerists with modems, anyone who follows the law and registers his modem with the phone company will be im- mediatelv notified of the extra charge. The Phone Company Replies in response to the issues raised here con- cerning the extra charges imposed on modem users, Walt Beiter, an official of Southwestern Bell of Oklahoma, told us: "With the spread of computer terminals in the home, we rec- ognize that the situation has changed. We're going to redesign our rates." The old rate schedule "didn't specify home, business, whatever. But we do realize that the condi- tions have changed. We've filed an applica- tion and expect to have hearings on this issue this fall." In the Oklahoma City and Tulsa areas, we have a flat-rate system for phone billing. We pay a basic flat rate of $8.95 for a residential phone line. This allows you to dial anywhere in the local calling area at no additional charge. If you want to attach your computer to the phone lines via a modem, that flat rate jumps to $45.90. Also, the additional monthly charge for Touch-Tone dialing almost triples from $1 .25 to $3,50, On top of the additional monthly rates. Southwestern Bell also retroactively charged me the difference between a business and residential phone installation because they "should have charged [me] for a business installation in the first place. [They] made a mistake." It is my opinion that if they charge me this rate, they must also charge everyone else who falls under the tariff. If they do start actively en- forcing the tariff, which they have the capability to do, there wouldn't be much modem use in Oklahoma. And modem sales in the state would almost cease entirely. If Oklahoma is just a test, and no one takes any concrete, effective action, there is a good pos- sibility that this is just the beginning of unreason- able charges for personal telecommunication.

Donald Thompson Do you invest in stocks or bonds? If you like to play the stock market, this program, originally written for the Commodore 64: or 8K-expanded VIC, can help you monitor your investments more carefidly- even helping you decide when to sell or buy. An Atari version is included. Of course no stock investment plan is fool- proof. You might want to try this program out by play- ing the market on paper before putting down any real money to see if it fits your investment psychology. Managing your stock investments can be a full- time job. "Stock Market Analyzer" provides the means to watch the progress of various stocks and record purchases and sales. The program includes a graph of the stock's price fluctuations and a guide to whether you should buy or sell a stock at any particular time. You can also see a list of transactions for each year for your tax records. The theory behind this program is that as stocks fluctuate, the best way to invest is to put only half as much as you otherwise would in a given stock. If the stock goes up, you make money. If the stock goes down, it becomes an even better buy, so you can then invest some of the money that you have in reserve. Using The Options Using Stock Market Analyzer is fairly easy. After typing in the program, SAVE it to tape or disk and then type RUN. A listing of stock abbrevia- tions will appear at the top of the screen, and you'll see seven options: 1 Search one stock 2 List stocks for any one month 3 Update DATA statements for new month 54 COMPUTEl November 1983 4 Buy or sell advice 5 Store data for transactions 6 Graph progress of any of your stocks 7 List transactions by year for tax purposes Sample stock entries are included in the pro- gram. It is a good idea to run the program with the examples before entering the data for your own portfolio. Doing this will give you a better idea of how the program works. You can then enter your own stock symbols, number of shares, and initial cost in place of the sample entries. You must update each stock price once a month or after each transaction. Before you update a stock price, make sure that you have included the necessary background data for the stock (lines 500-549). The information required for these lines is stock symbol, number of shares you have pur- chased (0 if you wish only to monitor the stock price), and net cost for the stock (again, 0 for monitoring only). Also set Y (in line 549) equal to the number of stocks being considered. Once you have entered this data, save the program and run it whenever you wish to update monthly stock prices or transactions. To update monthly stock prices, run the pro- gram and use option three to produce DATA state- ments. Press Y in response to the INPUT DATA prompt, and press RETURN over the data lines which appear on the screen. To update stock transactions, use option five to produce DATA statements. Again, press RETURN over the printed data lines. The DATA statements from these two options are in two forms. DATA state- ments based on monthly updates store the date for month and year. The DATA statements based on stock transactions store the date including year.

This difference allows the pro- gram to distinguish between monthly updates and transactions. If you want to clear out the oldest DATA, then, in immediate mode, type GOTO 20040. Each time the routine beginning at this line is executed, the first three DATA statements con- taining the earliest stock data will be deleted. Keep in mind that the program is designed to monitor the cost factor involved in buying and selling stocks, as well as the actual purchase price of a stock. Under normal circumstances, transac- tions under $300 are not practical since such transactions include high brokerage fees. Buy and sell advice is activated when the stock moves outside a range of values, which is determined in the subroutine beginning in line 850. There is, of course, no perfect method to guide investors in trading in the stock market.

Two fun-loving, but overworked Zerks— the main characters in your most popular game— have bro- ken loose and are trying to retire from the business. You try madly to stop them. If you can get a coin into the juke box, the Zerks get so caught up in the music, they drop everything and start dancing. You also try popping popcorn and making a pay phone ring— which immediately makes the Zerks stop, answer and start a wild con- versation. If you "win" the game, there are rib tickling cartoons by the Zerks to reward your efforts. It's a game full of sight gags, surprises and comedy. From the best. Br0derbund!

If you run into one, lightning will strike - and it only strikes once. The game includes five difficulty levels. Written for the unexpanded VIC, Atari and 64 versions are also included. It's a dark, stormy night with howling winds and bolts of lightning. You've got to get home - but first you must cross through the cemetery. Since you don't believe in ghosts, you won't have to worry about them. But the graveyard is very old and there are lots of tombstones. You have to hurry, but you can't bump into a grave marker- if you do, you'll be struck by lightning and it's goodbye, Charlie. How To Ploy "Goodbye Charlie" was originally written for the 68 COMPimi November19S3 unexpanded VIC. The Atari and 64 versions in- clude instructions within the programs. In the VIC version, four keys (Q, A, S, Z) are used to control movement. The L key is used to light up the screen when you need to peek at the graveyard. Success in this game depends on memory and perception. At the start, the computer will randomly place the tombstones and briefly light up the screen so you can see the obstacles. Get a good look. The first look is free, but any after that will cost you points. You will have to move across a dark screen relying only on your memory of the tombstones' locations. Remember - if you lose your nerve, you can get additional glimpses of the cemetery by pressing L, but this will subtract points from your score. Goodbye Charlie has five difficulty levels. After typing in and saving the program, try the Be Amazed! m-4 iHHr''5«i?"SSl!IE?E* ^'^'^W^ ^ H^ Telengard: How low can you go? Fifty We've created a subterranean monster, stories low. Tiiat's tile number of leveis in the TELEnQARD dungeon. Each labyrinthine level holds hundreds of dark chambers and tomb-like corridors for the mighty adventurer to ex- plore. It goes without saying that a shifting collection of hideous monsters with unpredictable behavior patterns can make life in the TELEHQARD maze quite interesting—and frequently quite short!

And because it's joy- stick controlled, you'll have to move faster than ever. But first you'll have to consider your strategy. Is it treasure you're after? Or glory? You'll live longer if you're greedy, but slaying mon- sters racks up a higher score. The Apshai series is the standard by which all other adventure games are judged. And novices will not survive.

You've got to stop sometime. The question is when. Right now you're in the lead. But the faster you go, the more gas you consume. And the quicker your tires wear down. If you do pull into the pits, though, you lose precious seconds. So it's up to you to make sure the pit CTew is quick with those tires. And careful with that gas. Otherwise, poof! you're out of the race. So what'll it be, Mario? Think your tires will hold up for another lap? Or should you play it safe and go get some new ones? Think it over.

Originally written on the VIC with joy- stick, versions are included for the 64 (with joystick) and the TI-99/4A with Extended BASIC. "Crazy Climber" is a game requiring manual dex- terity and judgment. With a joystick, you control the Crazy Climber as he scales the side of a brick building, avoiding windows and falling objects. The higher he climbs, the higher your score. The VIC Version First, type in and save Program 1. Then type in Program 2 and save it immediately following Pro- gram 1 on the same tape. When Program 1 is RUN, it will cause Program 2 to be loaded from tape and RUN automatically. When the game starts, you will see a demon- stration of the Crazy Climber in action. After this brief display, he will come to a stop, and you can start play by pressing the fire button. If the Crazy Climber falls, the game ends and your score is displayed. Simply press the fire but- ton to start another game. The climber will fall if any contact is made with a window. It's easy going until your score reaches 100. At this point, you'll have to contend with falling flowerpots. At 300, the flowerpots will stop falling, but you'll have to watch out for birds flying from the left side of the screen. If you reach 600, you've made it to the top of the building, and you start at the bottom of the next building. The 64 Version In this version, there are some major differences in play. First, plug the joystick into Port 1. Hit the space bar to start the game. Unlike the VIC ver- sion, you can climb onto a window as long as you have some contact with the wall. A variety of objects are tossed down at you - TVs, pianos, barbells, safes {it's one of those wild and crazy apartment buildings) - and they come twice as fast after your score reaches 150. This version also includes a high score feature. Pressing the space bar will start a new game. If you'd rather not type in the program, I'll make a copy (VIC version only) if you send a blank tape or disk, SASE, and $3 to: Ted Reynolds 145 North Broadway #IS Tooele, UT 84074 H£^ ANNOUNCING A NEW GAME SO ORIGINAL YOU NEED INSIDE SECRETS JUST TO SURVIVE...MUCH LESS WIN!

These objects are actually hurled down upon you by a relentless, sinister fellow who appears just briefly before throwing each object. If you are quick, vou can dodge these oncoming objects. No one knows why he throws things; it's a quirk. Be ready to meet the challenge. For as the game progress- es, the villain strikes with greater frequency. In this game, you move the Crazy Climber over a stationary building with the E, S, D, and X keys. The screen will wrap around when you reach the top or bottom. A hundred points are awarded for crossing the top of the screen, while an equal number are deducted for crossing the bottom. In addi- tion, ten points are given for each falling object that you avoid. The game ends when you are hit by a falling object or are pushed from a window by the villain. Thus, you are allowed to climb over windows in this version, but you're taking a chance. If the villain emerges while you are in a window, it's curtains for vou. (You'll be reheved to discover that the Crazy Climber carries a parachute.) One line in this program requires that you have a TI Speech Synthesizer connected to your TI-99/4A.

You may safely remove lines which contain onlv REMarks (no GOfOs will reference them). A challenge: See if you can get past round 25. Program 1: Alpha Blast -Atari This game is fun to play and will also sharpen your alphabetizing skills. How many times do you find yourself saying, "Q, R, S, T, U - yes, T comes before U"? I know I've often said it. The object of "Alpha Blast" is to shoot the four letters displayed on the screen in alphabetical order. Sounds simple enough, but it isn't. And to make it more difficult, you're being timed. For each correct answer you are awarded points based on the internal character set value. Since I am using lowercase letter values, an A would give you 97 points, G would give you 103 points, and so on. If you fail to shoot a letter in the correct order, the value of that letter will be subtracted from your score. If you get all four letters right, you will advance to the next round with new let- ters to shoot and less time in which to do it. If time runs out before you complete a round, the game ends, giving you a final score and the high score. This program uses a redefined character set 9i COMPUTE!

In its present form, the game requires a joystick. Moving the joystick in the direction of any letter will cause that letter to disappear. At the same time, the order of this response is recorded. After you have guessed the sequence of the first four letters, a new round begins with the appearance of four new letters. As the game continues, you are given less and less time to respond. The game ends when you can no longer provide four responses within the allotted time. Scoring for the game is calculated in lines 470 and 480. It is based on three factors: the round number, the time that it took you to respond, and the order of your answers. The faster you can provide the correct an- swers, the higher will be your score. For an incorrect response, points are deducted at a rate one and a half times the number awarded for correct answers. To convert this game to keyboard con- trol, substitute the following lines: 330 340 350 360 370 CALL CALL -U : : 0 IF tX GOTO IF ( X #3, 3?

Name PATH WAY George Trepal "Pathivay" is not a typical computer game. The com- puter is not an opponent - it simply keeps track of the game you play against another person. For VIC, 64, and Apple. The rules of the game are simple, but there are a few catches. Each player (two or three can play) starts off with four tokens at the start of a path. The first player to get all four tokens to the end of the path is the winner. To play, push the VIC's F7 key. The machine will return the number of spaces you can move. Each token is numbered 1, 2, 3, or 4. Press the appropriate number key for the token you want moved. If your token lands on another player's token, that token is sent back to the start of the path. If you land on your own token, that token becomes invisible until it is moved. As you play, you'll see that a wise strategy is required to win. The VIC version is written for the unmodified VIC, so disconnect any extra memory (except for the Super Expander). Game Movement Logic The positions of the tokens are stored in arrays and updated as the tokens are moved. Once a move is made, the arrays are compared to see if a token should be sent back to the start. The position of a token is a number which represents how many cells away the token is located from the start of the path. Each cell corresponds to a certain screen loca- tion, all of which are stored in DATA statements. For example, if a token were moved from cell 24 to cell 31, the machine would read the DATA from the start and put a path character in position 24 to erase the token. It would then return to the start of DATA and read to the thirty-first location, where the token is then printed to the screen. The 64 version is almost identical in play to the VIC version, although the playing field is larger. The Apple version uses the space bar in- stead of the F7 key used by the Commodore ver- sions. 106 COMPUTE! November 1963 Player 2 is about to roll the dice in the VIC version of "Pathway."

BOX 26714 • SALT LAKE CITY • UTAH '84126 Learning With Computers Glenn M Kleimon The stack of new books and magazines on my desk fell over yesterday. I took that as a sign that I should write about some of them in this month's column. I've selected four publications that will be useful to many teachers, parents, and students. The first two concern educational software, and the other two are new dictionaries of computer terms. In future columns, I will review new books on Logo, teaching computer literacy, and other topics. Courseware Report Card Each issue of the Courseware Report Card contains comprehensive reviews, written by experienced educators, of a variety of educational software packages. All types of educational programs are reviewed, including drill-and-practice, tutorials, simulations, games, authoring systems, classroom management systems, and versions of Logo and turtle graphics. The programs are for Apple, Radio Shack, Atari, and Commodore computers. Each review begins with a listing of the rele- vant subject areas, grade level, type of program, hardware requirements, price, and publisher's address. Then there is a brief summary of the program, followed by a very detailed description complete with pictures of the screen displays. Finally, there is an evaluation, divided into ratings of the program's overall performance and content, ease of use (for both students and teachers), error handling, appropriateness as a computer activity for students, documentation, and educational value. In each category, the program is given an A to F grade, and the reviewer explains why. A summary box displays the grades on each of the six criteria. I find the reviews in the Coursezvare Report Card to be more useful than any others I have seen. I like having a description of the program separate from the evaluation, and the screen pic- tures help me get a better idea of how the program looks. 1 also like the fact that the reviewers explain the grade they give the program on each of the criteria, so you can determine whether you agree with their views. This is especially important for 116 COMPUTE! November 1983 the appropriateness and educational value criteria, since educators disagree about the educational value of different activities and about which types of programs take best advantage of computers. Cotirseumre Report Card publishes two different sets of reviews - one for programs for elementary school students and the other for secondary school students. Each set can be purchased separately. Reviews are published five times during the school year, with at least 20 reviews each time. Each re- view is self-contained and three-hole punched, so you can conveniently file your copies by subject area, grade level, hardware compatibility, or how- ever you choose. Coursezuare Report Card is published by Educa- tional Insights, Inc., 150 West Carob Street, Comp- ton, CA 90220. Courseware In The Classroom Courseware in the Classroom: Selecting, Organizing and Using Educational Softivare, by Ann Lathrop and Bobby Goodson (published by Addison- Wesley, 1983), would be useful to anyone con- cerned with finding and evaluating educational software. This book is divided into six sections. Section 1 presents an overview of how com- puters can be used in all areas of the curriculum. Section 2 discusses six categories of software: (1) reinforcement and remediation (that is, drill- and-practice); (2) tutorials; (3) simulations and demonstrations; (4) problem-solving (for example, Logo, logic games); (5) program development aids (PILOT, shell games); and (6) tools for teachers (for example, classroom management and material preparation programs). Section 3 focuses on criteria for evaluating courseware. The authors begin by discussing the most important general questions to ask: "Does the software meet specific instructional objec- tives?" and "Does it take good advantage of the computer's capabilities?" They emphasize that there is no point in using computers for activities that could be done just as well without them. They go on to discuss other criteria for content; screen formats; ease of use for students and TheBe Now, you can get... 1NEW software programs featuring Stickybear^j;:^ the hottest-selling computer bear in America.

Three evaluation forms are given, with exam- ples of how they can be used. These forms were developed by the Northwest Regional Laboratory in Portland, Oregon; the National Council of Teachers of Mathematics; and the California Li- brary Media Consortium for Classroom Evaluation of Microcomputer Courseware. Section 4 covers the details of organizing and running a courseware library. Section 5 contains a directory of recom- mended courseware. The authors give a brief description of each program, with the information necessary to obtain it. They do not provide their own reviews, but give references to reviews that have appeared in magazines and other publica- tions. Only programs that ha\'e received positive reviews are listed. Section 6 consists of appendices containing copyright regulations; sources of evaluation guidelines, courseware reviews and courseware directories; and policies and procedures for se- lecting instructional materials. The Courseware Report Card and Courseware in tlie Classroom are mutually complementary. The former provides detailed reviews, and the latter provides information about doing your own re- views and finding other published reviews. Both publications will help educators find the software they need to make good use of computers with their students. Dictionaries Of Computer Terms A great many dictionaries of computer terms are available. Some are intended for children, some for adults who are novice computer users, and some for computer science professionals. My pet peeve about computer dictionaries is what I call "recursive definitions." These define technical terms by using other technical terms. You look up a word, and the definition contains several words that you don't know. You look up each of these in turn, but their definitions contain more words you don't know. For example, one dictionary defines instruction as follows: Data which causes a computer to carry out an operation and specifies the values or locations of all operands. A program controller examines each instruction and initiates the specified action. An instruc- tion usually contains an operator (indi- cating the type of command) and one or 118 COMPUTS! November 1983 more address parts, and sometimes a tag. The italicized words are defined elsewhere in the dictionary. How many people who looked up the meaning of "instruction" in a computer dic- tionary would know the computer jargon mean- ings of "locations," "operands," "address," and the other terms? If you are dedicated, you might look up each of these words and then look up the technical terms used in defining them. You might keep pursuing this through several levels of defi- nitions and then try to finally figure out the mean- ing of the original word in which you were inter- ested. However, I'd prefer a trip to the bookstore in search of a new dictionary. By the way, for those of you who are not familiar with the concept of recursion, a recursive procedure is one that can "call itself." Think of yourself as using afind-the-meaning-of-a-word pro- cedure. One part of this procedure would tell you that if a definition contains a word you do not know, you put the original word on hold and apply your find-the-meaning procedure to the new word. That is, the procedure reapplies itself to a new word - an example of recursion. When you find the meaning of the new word, you return to trying to understand the meaning of the original one. I have recently obtained two dictionaries that have mostly accurate and understandable defini- tions. Both are careful to provide clear examples and minimize the use of technical terms in defini- tions. For example, here are the definitions of "instruction" from the two dictionaries: A single operation to be executed by the computer. Instructions may move data, perform arithmetic and logic functions, control I/O devices, etc. A sequence of instructions forms a program. A single order that tells the computer to carry out some specific task. An instruc- tion in a program might tell the computer to operate a line printer, add two num- bers together, store information in mem- ory, or to perform any one of a number of other functions. Each instruction must be retrieved from memory, decoded and executed by the computer's central pro- cessing unit. A program is simply a series of instructions designed to solve a prob- lem or accomplish a task. The first definition is from the Illustrated Com- puter Dictionary, by the editors of Consumer Guide (Exeter Books, 1983). This dichonary is intended for computer novices. The second definition is from A Dictionary of Computer Words, by Robert W. Bly (Dell Publishing Company, 1983). This one is designed for students and contains many good analogies and humorous illustrations. © ^ 0, j>,o TomPEoicmnmam WE ASsamiDms It's a rare teacher who can make a child think learnins's fun. But we've found several of them. And they make Monkeymath™ more fun than your child ever dreamed an educational game could be. Of course Monkeymath helps give your child a better understanding of addition, subtraction, multiplication and division. That s the partyou'// like. But the part your c/j/W will like is Monkeymath's arcade- type action and animation, three skill levels and scoring. So, like any good arcade game, kids just can't stop playing it. In fact, in a recent issue of Antic magazine, David Plotkin called Monkeymath "... one of the most entrancing educational games ever writ- ten." (And Monkeynews™ and Monkeybuilder,™ our soon to be released reading comprehension and word recognition games will be every bit as entrancing.) So Monkeymath does more than help your child under- stand math— it teaches him that learning can be fun. And, as you can see, you don't find teachers like that just anywhere.

Buckminster Fuller - died this past July at the age of 86. Bucky influ- enced many people through his mathematical discoveries, and delighted millions more through his designs resulting from these discoveries. The geodesic dome stands as the most easily recog- nized of his creations. While we can appreciate the results of his thought, it is especially valuable for readers of this column to acquaint themselves with his "geometry of thinking" - a philosophy called "Synergetics." Synergetics is a mathematical formalism that, according to Fuller, embodies the design princi- ples of the physical universe. His exposition of these principles formed the subject of two books. Synergetics and Synergetics 2 (Macmillan, 1975 and 1979, respectively). While many people marvel at the beautiful simplicity of the geodesic dome or of the tensegrity structures Fuller discovered, few have taken the time to understand the underlying mathematical principles that led to the creation of these structures. It so happens that the principles of Fuller's geometry are easily grasped once one realizes that Synergetics is identical to the mathematical formalism of turtle geometry. Process Descriptions In turtle geometry one deals with process de- scriptions rather than with static descriptions of geometric figures. The two operators (FORWARD and RIGHT) change the state of the turtle and can be used to move it anywhere on a surface. As a 120 COMPUTEl November 1983 result, any static figure can be equivalently de- scribed by the process that created it. Process- based descriptions are central to Synergetics as well. While it is impossible to do justice to the for- malism of Synergetics in the short space of this article, several key concepts (and their equivalent expressions in turtle geometry) will be described. Each concept will be presented first from the per- spective of Synergetics and then from the per- spective of turtle geometry. 1. There is no continuum. There are no solid surfaces in the universe, no flat or smooth areas. Wherever scientists have looked, they have only uncovered localized energy fields which we per- ceive as discrete countable atoms. These atoms establish spatial relationships with other atoms through mutual optimization of their energy fields. The idea that the universe is composed of countable parts, that it is somehow granular, has an interesting expression in turtle geometry. Since the turtle responds to one command at a time, either it can move or it can turn. The fact that the turtle cannot turn while moving means that, in common with Synergetics, turtle geometry does not allow continuous curved surfaces. 2. Measurements in geometry need only two pa- rameters -frequency and angle. These two param- eters are sufficient to describe the location and placement of the nodes associated with the dis- crete quantized atoms which comprise the matter of our physical universe. The process by which one can move between any two nodes in the uni- verse is capable of being expressed in terms of a combination of linear movements along nodes 3 exceptional books join the DATAMOST library.

In turtle geometry, this central concept is expressed by the fact that combinations of the commands FORWARD and RIGHT are capable of repositioning the turtle to any desired location. Fuller's use of frequency instead of distance is a result of his desire to remove absolute scale from his geometry. 3. There is no simultaneity. The physical uni- verse is an unfolding scenario of nonsimultaneous (but partially overlapping) energy events. The finite speed of light governs our perception of the physical universe. A pair of events that appear to be simultaneous to one observer will appear to be nonsimultaneous to a second observer at another location. Since nothing happens "all at once," then all events and structures are the result of a process which created them. Traces of completed events resulting from separate and distinct pro- cesses may appear similar to each other. Simple Is Powerful A problem with static descriptions of systems is that they do not preserve the details of the pro- cesses which created them. Since the process con- tains more information than the static trace of its result, a process description is inherently more fundamental. Furthermore, process descriptions are often more compact than static descriptions. This surprising result lends force to the idea that simpler descriptions are more powerful. Turtle geometry defines objects through the description of the processes that create them. Computer-based implementations of turtle ge- ometry allow the explicit creation of procedures that describe the steps needed to create various geo- metrical shapes. These procedures can often be treated as extensions of the computer language itself. Logo is a prime example of a language that does this. There are many advantages of process-based descriptions. In conventional coordinate geom- etry, for example, the static description of a square located on a grid consists of specifying the coordi- nates of the square's corners. (0,50) (50,50) (0,0) (50,0) To create a new square at another location, one must create a new set of coordinates for each corner. In turtle geometry, once one has defined a procedure which creates a square, additional squares can be created by moving the turtle to a new location and using the "square" procedure at that point. 4. No tiao events can occupy the same space at the same time. Two energy events that are in close temporal and physical proximity will interact with each other in one of several ways, including: W a. tangential avoidance. One event can cross over or under another event. I!" b. modulated noninterference. If the energy events consist of a train of pulses and spaces, their paths can cross in a fashion similar to that displayed by two rows of cars which are changing lanes on a freeway. :illll> c. reflection. Two events can reflect from each other and acquire new paths. 122 COMPUTE!

Two events can, on achieving close proximity, perturb each other's path to avoid a collision. e. collision. When two energy events come into sufficiently close proximity, they may collide and smash into several other energy events which go off in a multitude of new paths. f. attainment of critical proximity. When two energy events become sufficiently close, they may go into orbit around each other. As a result of this coupling, they form a new system. There are six ways in which two energy events can interact. There is no way two energy events can occupy the same place at the same time. The concept of a dimensionless point resulting from the intersection of two lines is thus meaningless in the physical universe. In turtle geometry a secondary consequence of this concept is that different procedures can be used to create figures which appear to be identical. A triangle, for example, can be created by fol- lowing a left- or right-handed path. 124 COMPUH! November 1983 I'V Even though the finished figures are identical (such paths are called state change invariant), the fact that they result from different procedures can have important consequences. For example, an assembly-line robot that moves parts between three work stations will only perform its job prop- erly for one path description. 5. Irrational numbers are unnecessary. Synerget- ics involves a system of measurement based on discrete angles and countable frequency incre- ments. Space-filling structures are formed from poiyhedra, the minimum configuration of which is the tetrahedron. As the frequency of a structure is increased (by constructing poiyhedra with greater numbers of nodes), one approaches the construction of objects that appear nearly round. These objects are composed of a vast (but countable) number of discrete chords. Since such surfaces can be formed with any complexity desired, and since each surface is still bounded by chords, there is no need in Synergetics for irra- tional numbers such as pi. This is easily demonstrated in turtle geom- etry. To send the turtle on a circular trip, one might instruct it to take 360 steps, turning by one degree after each step.

Tanfly Corp Circular paths with different sizes can be created by changing the size of the step or by changing the amount turned at the end of each step. Instead of deaHng with the concepts of di- ameter and area, turtle geometry creates circles through the concepts of perimeter and curvature. 6. Meaningful descriptions of processes are local. Every celestial object is in motion with respect to every other object. These motions, viewed as a set, are nonsimultaneous. Furthermore, the interactions of these various motions vary widely over the eons of hme. As a result, any meaningful system of geometry must describe local processes without reference to an absolute origin. A description of a triangle must describe only the triangle itself and not be depend- ent on the reference frame in which the triangle is being envisioned. The concept of local descriptions of geometri- cal figures is central to turtle geometry. In contrast to conventional coordinate geometry, turtle pro- cedures provide intrinsic descriptions of objects. As mentioned before, a coordinate representation of a square applies to that one square only. The points on this one square are fixed in relationship to the origin of the coordinate system. In turtle geometry, on the other hand, a square is defined by the local steps that are needed to create it. A procedure such as: TO SQUARE REPEAT 4 [FORWARD 25 RIGHT 90] END will always create a square path regardless of the turtle's location and orientation. If, as Fuller believed. Synergetics provides the proper geometric framework with which to view the universe, then the incorporation of turtle geometry in various popular and user-friendly computer languages promises to help expand the awareness and creativity of all its users. The fact that many of the users of turtle geometry are chil- dren suggests that the child's view of the physical universe might have more power than we ever ex- pected.

You must defend your home base against the increasiiigh/ fast character "bond^s." Three skill levels, as well as final score and rank, are included. "Key Panic" is a multilevel, fast-action game in which you must shoot descending characters that threaten your protective shields at the bottom of the screen. Written on an Atari 800, the program has been condensed so it can run on an 8K Atari. It was originally designed to improve typing speed and key recognition (which it does), but it also turned out to be enjoyable as a game, too, with lots of player options. Choose Your Bombs After typing in the program, be sure to SAVE it. When you run Key Panic, you will be given several options. First, use the SELECT key to choose one of three skill levels. You will probably have to play the game a few times to find the best level for you. Next, use the OPTION key to choose letters, numbers, or letters and numbers. This will deter- mine what kind of "bombs" you'll have to contend with. Now you're ready to play. Press START and the panic begins. As each character scrolls down, you must identify it and quickly press the cor- responding key. At the bottom of the screen, you'l! have three protective shields. If you miss the right key or hesitate, the character bomb will strike and destroy your shield with a loud explosion. If you lose all three shields, the game ends and you will receive a score and rank. If you're able to fend off all the characters in the first wave (approximately 50), there will be a 128 COMPUTE! November 1983 short pause before the speedier second wave be- gins. There is a total of five waves, each progres- sively faster. Make it through all five waves and you win. You'll then receive a score and rank. Press START for another game.

It not only plays fast, but also improves typing skills. ' The Protection Of QWERT Your mission in "Typo Invaders" is to protect the city of QWERT from the fatal alphabet bombs. As each letter drops, press the ap- propriate key before the bombs explode in the city. With each pass, the bombs drop from an increasingly lower altitude. At the start of the game, you must choose a difficulty level (0 to 9). Points are awarded according to this level as well as the distance from the city when a bomb is destroyed. The game ends when QWERT is destroyed. The program uses approximately 2700 bytes, which, of course, works fine with an unexpanded VIC. However, if your VIC has 8K or more expansion, change line 100 to: 100 SC = 4095:CC = 37887 Repeated exposure to Typo Invaders may have certain positive educational effects, such as a drastic increase in typing speed.

Computers And Society Dovid D Thornburg, Associote Editor This two-part series on program/languages began in last month's column with a discussion 0/ VisiCalc mtd Rocky's Boots. The concluding column examines the program Dancing Bear as a language and explores the potential injpact of these types of languages. That's Not A Program, That's A Language In last month's column, I explored the idea that some software offerings that we might consider application programs are, in reality, computer languages. In order for me to conclude that a pro- gram is a language, it must have the following characteristics: 1. A computer language must allow the user to create computer-based activities that are custom-tailored to the user's needs. 2. The language must have a vocabulary and a grammar. 3. The user should be able to edit and save his or her program. 4. The user should be able to run the program. I have read recently that some people think of word processing programs as languages. I dis- agree with this assessment of word processors since the word processor doesn't use the user's text to control the computer's activities. A word processor is simply a program designed to let users create text files that can be printed out. Ad- mittedly, there are word processors that allow the creation of user-defined "macros" to perform complex formatting functions. But, while these macros are computer programs, this function is not a pivotal part of most word processing systems. Dancing Bear As A Language One program that is most definitely a language is Dancing Bear from Koala Technologies. 134 COMPUTE! Novembet 1983 Koala is the manufacturer of the low-cost KoalaPad Touch Tablet which allows the simple use of a finger or stylus to convey position infor- mation to the computer. One of the features of this device is its use of overlays that let the tablet be used both as a graphics or position input device and as a special- purpose keyboard. Dancing Bear (currently available for the VIC) is a program which lets the user make an animated bear do a dance on the display screen. The stage on which the bear dances can be decorated with props by the user, and the bear can dance to user- defined music. This program (developed by Audio Light) uses the KoalaPad for all its input. To see why this program is a language, we will briefly examine how it is used. Creating A Dance Program Dancing Bear uses the tablet overlay shown below. ATARI SOFTWARE FOR THE WHOIE FAMILY Here are four software packages designed for the different people in your family. A BASIC COMPILER FOR THE PRO- GRAMMER ABC (A BASiC Compiler) auto- matically trans- lates Atari BASIC programs into high-performance integer P-code that runs up to 12 times faster! Perfect for devel- oping system soft- ware and commer- cial games, ABC accepts most BASIC programs {unless floating point dependent) with little or no modification. Compiled P-code is a self-standing DOS object module that is unLISTable and runs without the BASIC cartridge. ABC allows expressions in DIM, GOTO, GOSUB, and RESTORE state- ments, doesn't require you to re-order lines, and fully supports string and sub-string operations. Give your BASIC programs the look and "feel" of professional prod- ucts with ABC. 40K Disk $69.95. Manual alone $9.95 (credited toward compiler purchase). MAKEBOOT lets you create self- booting disk or cassette versions of your ABC compiled software. Re- duces overall program load time and saves memory and disk space by eliminating DOS. 40K Disk SM.95. AN EDUCATIONAL TOY FOR PRE-SCHOOLERS Monarch is proud to present SofToy. an educational program smart enough to act simple. Bells ring, balls bounce, owls hoot as SofToy and its colorful interactive display gently introduce children (two years and older) to spatial relations, letters, numbers, even elementary programming! SofToy lets kids be- come familiar with computers, without arbitrary demands, competition, or intimidation. SofToy grows with chil- dren, too. At more difficult levels, the match game is a real challenge for the whole family. 24K Disk $29.95. TOOLS FOR THE SERIOUS USER Power Toote / combines four sophisticated text processing tools on one easy-to-use utility disk. D/FF shows you differences between two ATASCII text files: for example, changes you made in a pro- gram or document from one version to the next. Manually searching for a particular text file can take hours. But now, with SEARCH, you specify a search string and a list of files. SEARCH examines the files and points out which ones have that string. You'll never lose your Fudge Brownie recipe again! CHANGE IS a powerful search and replace utiiity that operates on multiple files with one command. For example, you could change character names throughout your novel with a single command, even if each chapter is a separate file. The special pattern-matching and multiple disk capabilities of SEARCH and CHANGE are an added plus. TRANSUT \e\s you swap one char- acter set for another (for example, upper case for lower case) throughout a file with one command. PowerTools I is ideal for professional business and software development text applications. 40K Disk $34.95.

To create a new dance program, the user selects the DANCING option from the startup menu and presses NEW on the tablet overlay. The bear is then shown in its starting position in the center of the stage. In the upper-left part of the screen you can see a small bear icon with an arrow underneath it. This is the program listing. To create the next step of the dance, we might press NEXT and turn the bear's head a little to the left and lift its left leg. As you can see, these changes are reflected in the listing. The next few figures show other steps in the sequence of this dance. 136 COMPUTE' November 1933 CANON AS-100^« HEATH/ X ZENITH Z-1Q0^" OSBORNE^ RET/CBM^" SUPERBRAIN^" CP/M DISKS DISKETTES DYNACOMP The Leading Distributor Of Microcomputer Software PRESENTS HOME FINANCE CARD GAMES PERSONAL FINANCE SYSTEM (ALL) $ 39,95 BRIDGE MASTER (ALL) $ 29.95 TAX OPTIMIZER (ALL) $ 59.95 GIN RUMMY (APPLE) $ 22.95 MICROCOMPUTER STOCKS (ALL) $ 59.95 POKER PARTY (ALL) $ 23.95 MICROCOMPUi HR BONDS (ALL) $ 59.95 BLACKJACK COACH (ALL) $ 33.95 BUDGET MODEL ANALYZER (ATARI) S 23.95 EUCHRE (ATARI) $ 19.95 PERSONAL BALANCE SHEET (OSBORNE) $ 29.95 STOCK MASTER/STOCK PLOT (APPLE) $ 59.95 WAR GAMES NY INDEX (ATARI) $ 29.95 LEIPZIG 1813 (ATARI) $ 33.95 STOCKAID (ATARI) $ 29.95 SHILOH 1862 (ATARI) $ 33.95 PORTFOLIO MANAGEMENT (APPLE/OSB) $ 69.95 IRONCLADS (CPM) $ 29.95 INVESTING ADVISOR (TRS) $ 39.95 INVESTMENT MANAGEMENT ADVENTURE (ATARI/IBM) S 49.95 CRANSTON MANOR (CPM) $ 19.95 OPTIONS ANALYSIS (TRS/OSB/APPLE) $ 99.95 WINDMERE ESTATE (NORTH STAR/APPLE) $ 29.95 BUSINl':SS ZODIAC CASTLE (NORTH STAR/APPLE) S 29.95 FINANCIAL MANAGEMENT STARSHIP LANDING PARTY (TRS) $ 19.95 (NORTH STAR) $149.95 GENESIS-THE CREATOR (APPLE) S 49.95 MAIL MASTER (ATARI) S 39.95 VALLEY OF THE KINGS (ATARI) , $ 29.95 PAYTIVE (APPLE) $149.95 LIFE CYCLE ANALYSIS (APPLE) $ 39.95 GAMES DATA RETRIEVAL SYSTEM (ATARI/CPM I 29.95 VALDEZ(ALL) $ 23.95 OPTIMAC (TRS/ APPLE) $ 43.95 FLIGHT SIMULATOR (ALL) $ 23.95 BOOKKEEP(CPM) S 69.95 BACKGAMMON 2.0 (ALL) $ 23.95 CUSTOMER PROFILE (OSBORNE) $ 59.95 MANAGEMENT SIMULATOR (ALL) $ 29.95 CHESS MASTER (CPM/TRS) $ 23.95 EDUCATION STARBASE3.2(ALL) $ 17.95 HODGE PODGE (APPLE/TRS) $ 18.95 CACTUS LEAGUE BASEBALL (ATARI) $ 19.95 CHILDREN'S CARROUSEL (APPLE) $ 19.95 FINAL ASSEMBLY (ATARI) $ 19.95 TEACHER'S AIDE (ALL) $ 17.95 TEACHER'S GRADE BOOK (APPLE) $ 49.95 ENGINEERING/SI ATISTICS PLAYER PIANO (ATARI) S 19.95 DIGITAL FILTER (ALL) $ 53.95 SPELL IT (APPLE) $ 19.95 HARMONIC ANALYZER (ALL) $ 33.95 ELIZA II (ALL except APPLE) S 19.95 BASIC SCIENTIFIC SUBS.

This listing can be edited, saved, or run. A REPEAT function allows any portion of the dance to be repeated as many times as desired. The finished dance can be tested, edited, merged with user-defined (or predefined) music, and the stage can be outfitted with props. The prop room lets you outfit the stage with blocks and labels. The set can be as elaborate or as simple as you desire. The music editor uses the KoalaPad to pick up notes and place them on a stave. As with the dance itself, the music can be tested and edited if desired. The enhre dance program (props, music, and bear motions) can be saved on tape for later use. If we accept that Dancing Bear is, in fact, a programming language (along with VisiCalc and Rocky's Boots), one might legitimately ask "Who cares?" I guess the point is that languages are funda- mentally more powerful than application pro- grams because they let the user gain control over the computer system. Admittedly, VisiCalc, 138 COMPUni November 1983 Rocky's Boots, and Dancing Bear don't offer the degree of access to the computer found in lan- guages such as PILOT and Logo, but they offer far more control than fixed-function application programs. The personal computer is unlike any other appliance to ever grace the home. Where the washer, stove, or television has fixed functional- ity, the computer is, by design, a general-purpose machine. Ultimately, effective use of this machine will only come when each user feels comfortable in molding the computer's applications to his or her own needs. This molding process requires programming skills on the user's part. Since the beginning of the personal computer industry, we have been trained to believe that computer programs were linear strings of text. In this regard, the only differences between BASIC, Pascal, and Logo are grammatical. VisiCalc, Rocky's Boots, Dancing Bear, and other languages of this sort point to another type of language - one that is more parallel than serial in its programming style. It is significant that these three programs (and others that have similar characteristics) are designed for nonprogrammers to use. I see the continued development of languages of this type as a revolutionary force that will finally make programming a natural activity for every user of a personal computer. © Use the card in the back of this magazine to order your COMPUTE!

Elsewhere in this issue (in my "The World Inside The Computer" column) I begin a discussion about the difference between computer literacy and computer intimacy. I'd like to continue that discus- sion in this column. Let's look at the myths that make adults so anxious and fearful about computers. We'll see how most adults who want to know more about computers should become intimate with com- puters before they try to become computer literate. The Myth Of The Klutzy Adult A per\'asive and pernicious myth is being spread unthinkingly throughout our society. The mvth is that our children are whizzes with computers, but we adults are klutzes. This myth is almost com- pletely ungrounded in fact. Why are children so good with computers? They are good because they see only the colorful, musical, exciting side of com- puters. The first time they meet a computer, it is wearing a smile. Children are spurred to master computers be- cause they are so attractive. When we adults see this side of computers, we, too, can master com- puters just as fast, just as happily as our children. Trust Your Feelings What is computer intimacy? What is intimacy? Inh- macy is a gut feeling. You know you have become intimate with your computer when you are totallv comfortable and relaxed with it, when using it be- comes a pleasure rather than a chore, and when you develop excuses just to spend more time with it. When you begin to think your computer is lovable, that's when you know the two of you are becoming intimate. Getting to know a computer can be like getting to know an attractive yet intimidating member of the opposite sex. 1 think there is a great similarity 140 COMPUTE! November 1983 between my first experiences with girls and dahng, and the average person's first experience with com- puters. When the average person first looks at com- puters, he or she feels the same sense of fear and anxiety that I felt when I gazed across the gym- nasium floor at the girls clustered on the opposite side of the room. That was my first school dance. Computers evoke the same sense of shyness, yet they can also be tremendously attractive, even seductive. A New Love Affair For almost 75 years, Americans have had a love affair with their cars. Computers wiU soon be like cars. Like cars, they will remain machines, and our servants, yet they will also have an emotional, gut- level appeal that will turn people on and bind them to them. The kind of car we drive depends on the kind of person we are or would like to be. Our car's ap- pearance, model, and year often accurately reflect our values and the kind of image we want to project to our fellow human beings. Cars project all sorts of images. They can be inconspicuous, efficient, and sedate, or thev can be clunky ragamuffins. They can be flamboyant, garish, and ostentatious, or they can be sensual and adventurous. Computers, too, will soon reflect our lifestyles, values, and self-image. They will also reflect our needs. Like cars, computers will come with model names pulled from the animal kingdom. Depending on our needs, we'll buy a Cobra (fast as lightning), or a Hippopotamus (it digests huge quantities of information), the St. Bernard (it saves your life in tight situations), the Peacock (it really struts its stuff), or the Donkey (slow and stubborn, but real dependable). Computers, like cars, can evoke a passionate attachment, a rush of affection. But to inspire real intimacy they must throb to life at the turn of a key, and they must get us where we're going - the faster the better. A computer can be seductive and lovable, but it is not an end in itself. Many people can get excited about a computer for its own sake.

In the future, computers will promise even more than they do today. But let's make sure they keep those promises. More Than Tools Computers are only machines, but they are more than tools. A hammer is a tool. So is a broom. But can you get intimate with a hammer or a broom? Not easily. Yet it's easy to get intimate with a com- puter, because computers are more than work- horses and tools. Computers obey our commands. They carry on conversations. They listen to us. They are infinitely patient. They can be friendly, playful, even silly. Friendly computers? Playful computers? Silly computers? Where do you find them? Just ask a child. Children love computers because they use computers to learn and have fun. But why can't adults learn on computers, too? And why should kids have all the fun? Adults who peek over kids' shoulders at their programs find that the programs are challenging, enjoyable, and enlightening. Adults can use these programs, overcome their fears about computers, and relieve their com- puter anxiety. Adults can get to be just as good with computers as kids, and they can have just as much fun. Computers That Frown And Look Mean Most adults still think that computers are dry, cold, and unfriendly. No wonder! Most computers in the past were number crunchers, bill collectors, and tax watchdogs. Even today's computers, in their heart of hearts, do nothing more than juggle ones and zeros. But computers don't have to be technical and boring. They can be funny - if you just add people. The relationship between com- puters and people is often hilarious, if we keep a sense of humor. It pays to look at the lighter side of this relationship, and if we do, we find it helps to break down the barrier of fear separating us from the computer. Coming Out Of The Closet In recent years all sorts of groups have come out of the closet and have honestly revealed who they are and what they stand for. It's time that com- puter lovers do the same. As a person who is on extremely intimate terms with his computer (it follows me into my bathroom and into my bed), I'd like to confess here and now one of the most closely guarded secrets of our relationship: My relationship with computers is not rational. This is a shocking revelation, but it is true. My relationship with my computers is emotional, 142 COMPUTE! November 1983 quirky, and antic. It is infuriating, enlightening, and silly. It is happy, frustrating, and ecstatic. But it is rarely rational. And I contend that this is true throughout our society among the millions of computers and computer users. A rational re- lationship between a human being and a computer is the exception rather than the rule. Take today. My assistant and I were working on a personal computer. We were sailing along, turning out letters, articles, and forms at a swift, productive pace. The world looked bright, and we were happy. Then disaster struck. The computer made a mistake. The computer's mistake was only a little one. It wouldn't save any of our text files on disk so that we could print them out on the computer printer. Until it made its mistake, the computer had been behaving itself. I felt very close to the com- puter and was extremely fond of it. After the computer made its mistake, I had a change in heart. No matter what 1 did, the com- puter wouldn't save or print my files. So I hated the computer. I called it names. I threatened to walk out on it, abandon it, put it up for adoption. Now I ask you, does this sound like a rational relationship? A rational relationship must have at least two parties who are rational. First we look at the first partner- the human being. Occasionally, philos- ophers have proposed that humans are rational, but most of us know otherwise. Next let's look at computers. This is more of a problem. Computers are incredibly complex machines, composed of millions of interacting circuits and thousands upon thousands of oper- ating instructions, rules, and conditions. Com- puters are too complex to be simple, too complex to be totally rational. Nevertheless, people think they are rational. For example, the popular wisdom now contains two catchy phrases that most people unques- tioningly believe: First: Computers don't make mistakes. Only people make mistakes. Second: Computers do only what you tell them to. As I mentioned, I am extremely intimate with computers. Since I am in this privileged position (along with two or three million children), you would think that I would be able to see through the popular wisdom and realize that the two catchy phrases above are pure hogwash - myths and nothing more. Alas! I am as much a victim of these myths as the next human being, at least when I am working with my assistant.

Why, her, of course. Take the other day. I was upstairs in my study and Darshi, my assistant, was downstairs in the office. All of a sudden, she yelled, "Fred! Come quick! The computer's going crazy!" Sure enough, the cursor was rolling across the screen wiping out the words almost like Ms. Pac-Man rushing around devouring ciots. I pushed every button on the keyboard, but nothing worked. The cursor was determined to eat the whole file. Finally, in desperation, I turned off the com- puter. Then I turned toward Darshi. "What did you do?" I said, in a not very friendly voice. "The computer was fine just a few minutes ago. You must have done something to mess it up." Sadly, this was the last thing Darshi needed to hear. She was already extremely tiiriid around the computer and afraid that the next button she typed might blow the computer up. When I ac- cused her of her worst fear, she looked ill and ran out of the office. Why had 1 blamed Darshi? I blamed her be- cause she was a beginning user and a human being. Those two facts alone were enough evi- dence to convict her. Sometimes computers are agreeable, respon- sive, and meek. They do everything you tell them to. But then, a moment later, without any warning, they turn on you. They suffer amnesia. They pout and get sullen and write gobbledygook all over your lovely files. Or they act crazy and start doing awful things like eating up the words on your picture screen. And they get out of control. Then the only way to get their attention is to switch off their power. This, of course, is an undesirable and drastic solution. But, sometimes, it's the only way to make them come to their senses. A Little Breattiing Room When you are in the middle of a squabble with your computer, it doesn't seem very funny. How- ever, after things have quieted down, and you look back, you might be able to put things into perspective, and maybe even laugh about them. But one thing you should not do is pretend that you and your computer have a rational re- lationship. It is anything but that. It may be quiet, sedate, and low key. Or it might be wild and boisterous. But it is not rational. It can't be. You're not rational. The computer's not rational. So how can your relationship be rational? The sooner people stop looking at their re- lationship with computers as rational, the sooner they will become intimate with computers and learn to accept them for what they are. Computers are moody and complex creatures. But they try hard to please you. They really do. © COMMODORE 64™ SOFTWARE 0 f. ■■■■■ SPRITEMASTER" is not jusl another sprite alitor.
