INTRODUCING APPLE SOFTWARE BANK CONTRIBUTED PROGRAMS alog of user contributed sftware, and express our thanks to fl those both inside and outside of Apple Computer whose efforts made it possible. The purpose of the contributed section of the software bank is to allow APPLE users to share pro- grams among themselves easily and at very low cost. By setting up a system to make this possible, we at APPLE hope to bring about a cross- fertilization of the user community, with better programs and applica- tions ideas as the result. Here is a brief description of the program. More details will be found in the enclosed catalog. As APPLE receives contributed programs, they are screened. The necessary documentation is assem- bled, and written catalog descrip- tions are produced for each program accepted. The author is then sent a $25 APPLE merchandise certificate. Periodically, the available pro- grams will be assembled onto diskettes, bulk duplicated, and supplied to APPLE dealers at a modest cost. The dealers will have unlimited reproduction rights to the programs on each diskette. As each diskette is released, APPLE will distribute a catalog of its con- tents to you along with CONTACT. When you see something you like, just call or visit your local dealer for a copy. The library is a resource. In it you will find some programs you can use as is, some you can improve upon, and some that may not interest you at all. That’s as it should be. Use what you can, send in your improvements, and let’s work together to build a super library! Oh, about the Bard on the cover. His image is one of many graphics demonstrations available on the first set of Software Bank diskettes. It was produced with a modified facsimile machine that digitized the original artwork, and a graphic processing program ona PDP-11/03 that reduced the image to an 8K byte database. It can now be displayed by the Apple in the Hi-Res Graphics mode. LOCAL USER GROUPS ...and the beat goes on With this issue of CONTACT, we’re pleased to add five more groups to the rapidly growing list of APPLE user groups: CALIFORNIA — APPLE CORE Scott Kamins Box 4816 San Francisco, CA 94101 OREGON — STEMS FROM APPLE Ken He tt 9195 S.W.

If you’re interested in forming or joining an APPLE user group in your area, call or visit your local APPLE dealer; he’ll be glad to help. And if you know of an APPLE group that’s not yet been listed in this newsletter (see CONTACT No. 1 and No. 2 for the listings of the groups that we know about), write us here at APPLE. Direct your note to Phil Roybal, marketing manager. LOOKING AHEAD ... Catalogs, Catalogs With this issue of CONTACT we've included an APPLE catalog and a price list. If they’ve been swiped by the time you read this, or if you'd like another set “fora friend,” just drop us a line — we'll be glad to send you the literature that you request. Note, too, that this mailing includes the first catalog of User Contributed Software, with instruc- tions on how to get it! EDITORIAL --. ON USer groups. by Jim Hoyt (Silicon Apple Programming Society) The name says it quite explic- itly. USER GROUP: individuals drawn together by a common interest in getting maximum benefit from their computer investment. Member benefits are manyfold. For the newcomer, programming techniques are explained, the inner workings of the computer made more clear. The answers to many beginner’s questions are found right here. More experienced members can get help or help others with soft- ware and hardware design. (Some of the things being done would amaze you: APPLE controlled cassette I/O and lower-case displays to name only two!) All members benefit from the group’s library. There is probably no better place to get low cost soft- ware or that back issue of the mag- azine you need, And many members enjoy newsletters published by their group which supplement our own with hints, local news, and application ideas. The growth of the personal computer industry depends on you, the USER. Join a group. If there is no local group, consider starting one. A group ties it all together! PATCHES AND PROGRESS APPLESOFT II and DOS ... squashing a bug If (in the DOS) you try to load a program that had been saved under RAM APPLESOFT II, but you are now using the ROM card version, your program will not run correctly. To get around this problem, load your program and then type CALL 54514 and your program will be correct. Similarly, a program that was saved onto diskette from the ROM card version and later loaded under RAM APPLESOFT II will also cause problems. Simply type CALL 3314 and your program will be correct. You can now save it onto tape. The earliest production DOS had a problem: when in APPL SOFT II, any Read or Write ments with line numbers o higher would be ignored. To solve this problem on any disks you may INIT in the future, bring up the DOS, remove the Write Protect sticker from your system’s master diskette, and then type: >PR#n (boot your system) >BLOAD RAWDOS >(hit Reset) *25D6:4C DS 3F *25DC:2E *3FD5:E8 FO 1 60 4C DD 25 *3D0G >BSAVE RAWDOS, A$1B00, L$2500 Any new masters created from this original master diskette will now work properly. Two corrections to CONTACT 2, June °78 There is one correction to be made in each of two program list- ings in the HOW TO section of the last issue of CONTACT. — The CONVERT program on © 6: statement 251 should read *T<>0 THEN NEXT B:B=B+1: IF B<E THEN 40 The HOW TO SET LOMEM WITHOUT HARDLY TRYING program on page 7: we should have tried harder. We now hasten to point out that, in statement 40, B cannot be a variable, since setting the new LOMEM will destroy the variables (as we ourselves said, in the paragraph just preceding the listing). The concept works, but make sure that you POKE in numbers in that line, not variables. contact 3/the user group newsletter for sept. 1978 @oppic computer inc. Cockpit errors and DOS A high percentage — 75 per cent, to be precise — of disk errors found so far are due to users trying to run APPLESOFT II by typing “RUN APPLESOFT.” This seems reasonable, but APPLE II doesn’t see it quite that way. As a result (among other things) you cannot reload programs saved on disk. To get things to come out right —all pointers where they should be, etc. —, from Integer BASIC simply type FP (Carriage Return) and you'll bring in APPLESOFT II, pointers and all. To get back to Integer BASIC simply type INT. About that Communications Card manual... We’ve put together some addi- tional information that will be needed by many of you using our Communications Card. Included are a routine for use with low-speed printers, information on setting the card’s status register, information on setting up a 1200-baud data rate, and a number of other inter- esting tidbits, as well. We will be including this adden- dum to the card manual with all future card shipments, and we’ll also be distributing it to all our dealers. So if you already have an APPLE Communications Card, just call your APPLE dealer to get your copy of the additional card info — it’ll be available about the time that you read this. BITS AND PIECES APPLE software bank contributors ..-please take note Document, document, docu- ment. It would be difficult for you to give us too much information about a program that you send us — we need to know as much (and sometimes more) about your pro- gram contribution as you can tell us. And never assume that potential users of your program are as clever as you; instead, assume that they know nothing — not even when to hit RETURN! Remember: The care you take in explaining your program is the only guarantee that it will be usable by anyone else. SAVE, then SAVE again. SAVE your program twice, one recording after the other, on the same cassette. By doing this you give yourself, and us, a safety factor in that if our computer cannot read the first SAVE, perhaps it will be able to read the second. (As you know, not all recorders are created equal.) By the way, please add your name and address to the program listing with REM statements before you save it, so that there will be no question as to whose program we’re running when we try it out. LOAD, check, then give yourself credit. After you SAVE your pro- gram, turn OFF the Apple to clear the memory space you’ve been using, then power it up and LOAD the program to be sure that it does in fact load and run. Finally, protect. After saving your program, make sure that it cannot be erased. Every cassette includes a write/protect feature in the form of two small plastic tabs on the edge of the cassette oppo- site its business end. When these tabs are pushed in, pulled out, or otherwise gotten out of the way, the cassette can no longer be written into. Clearing the air. We make no profit from your contributions to the user portion of the APPLE software bank. We set up this por- tion of the bank simply to encourage and to ease the exchange of pro- grams among APPLE users. The honorarium that we pay for contri- butions to this portion of the bank is merely our way of encouraging such contributions. From time to time, of course, APPLE does purchase software, and does so at the fair market value. Such purchases are negotiated indi- vidually, based upon market condi- tions, applicability of the product, etc. THE MiIST.... ..- ASCII character equivalents The following table presents decimal-number equivalents and APPLE keyboard equivalents to ASCII (American Standard Code for Information Interchange) char- acters. That is, if you were to scan the keyboard directly in BASIC, these are the characters that you would read; or, if you were to go into memory, these characters would appear as string-variable values. contact 3/the user group newsletter for sept. 1978 @oppic computer inc. In the APPLE keyboard column, read SMC as a SHIFT/CONTROL-M BC as CONTROL:B, etc. The deci- mal numbers listed are those before clearing of the keyboard strobe; after clearing of the strobe, the number is the listed value minus 128 (e.g., after clearing of the strobe, 145 becomes 17). If an APPLE keyboard equivalent doesn’t exist, or if there is no deci- mal equivalent, then the table shows a double dash (-: the key- board equivalent is identical to the ASCII character itself, then the table shows “‘sa.”’. Such information can make your programming life much easier, because it lets you get keyboard data directly into a BASIC program without the use of an INPUT state- ment. As you know, INPUT state- ments can be limiting as, for example, when you type ina line and the screen yells SYNTAX ERROR at you. Well, what is the error? It may take a long time to find If, on the other hand, the key- strokes are picked directly off the keyboard then you — the program- mer — are in command every step of the way; you make the decisions as to what goes and what does not, and in a way that tells you exactly what’s wrong as you go wrong. You can see one way in which this idea is applied in ‘Being Precise in INTEGER,” in this issue’s HOW TO section. In this Multiple Preci- sion Arithmetic listing, statements 2500—2610 input data directly from the keyboard; they tell you exactly what’s happening, the nature of any error you may have committed, etc. — and all by making use of the equivalence in the table presented here.

HOW TO A moving experience (Adapted from the Apple Core Newsletter, San Francisco, CA). Ordinarily, APPLE displays only Page | of its memory (locations 1024 to 2047). But it is possible to display Page 2 (locations 2048 to 3071) as well; and if you know how to do it, use of Page 2 will give you black screens in a hurry, and snap your graphics and/or text material cleanly on and off. Before you can use Page 2, how- ever, you must tell APPLE not to put any variables at locations lower than 3072; in other words set LOMEM:3072. After you’ve done this, you’re free to move the con- tents of Page | to Page 2, reload Page 1 with new data, and switch back and forth between the two pages. Here’s how to do it, using the general-purpose block move- ment routines built into Apple’s monitor. POKE 60, (old starting address mod 256) POKE 61, (old starting address / 256) POKE 62, (old ending address mod 256) POKE 63, (old ending address | 256) POKE 66, (new starting address mod 256) POKE 67, (new starting address / 256) CALL -468 (the actual move command) Now, to use Page 2 (remember to set LOMEM to 3072 or higher): 10 POKE 60,0:POKE 61,4:POKE 62,255 :POKE 63,7 :POKE 66,0:POKE 67,8: CALL 468: POKE -16299,0 To switch back and forth between Pages | and 2: POKE -16299,0 (displays Page 2) POKE -16300,0 (displays Page 1) If both pages contain similar graphics figures, then switching between the pages will yield simple animation; further effects may be gleaned from an inspection of the list of POKEs on page 30 of the APPLE II Reference Manual. (NOTE: Don't try this with APPLE- SOFT in RAM. It starts at hex 800 — the second page of graphic space. A block move into that area will send your APPLESOFT BASIC into the bit bucket!) The name of the game is the saving of the name If you’re an APPLESOFT II user working with, say, an inventory list with names, then you're in a bit of trouble if you want to SAVE the complete list to cassette tape, names and all: APPLESOFT II will save the numbers but not the names (strings). (Of course, the nicest way to SAVE such a list is to disk.) If you need to save strings to tape however, the following pro- gram will do the job very nicely. Note that statement 10 creates space for the strings; 1010 gives you information about free memory space and how far up the variables are; 1050 writes out the length of the tape’s string area; and 1070 writes all the desired information to tape.

Lining things up, point by point Since most BASICs justify (i.e., line up) to the left-most column, a display of multi-digit, decimal- pointed numbers can be awkward to read and somewhat unattractive. A solution to this problem would be to use a tabulation rou- tine that ‘‘justifies (or lines up) on the decimal point.”’ Such a routine would position the numbers in a column so that the decimal points are vertically aligned. The short pro- gram listed below does exactly that. Statements 10 through SO are merely a demonstration routine that yields the sample run shown at the end of the listing. Statements 2000 through 2140 contain the routine that actually does the work. In effect, the routine aligns the numbers by right-justifying to the digit left of the decimal point, then tacks on the decimal point and the remaining digits to the right of the decimal point.

Such a limitation is, at its best, frustrat- ing, and, at its worst, infuriating. Consider, for example, the business- man who daily deals with foreign currencies, for which the basic monetary unit may be very, very small. What’s a fella’ to do? Well, what he has to do is to go to multiple-precision arithmetic by means of a routine such as we present here. While this example is for addition only, it is readily adapt- able to subtraction, multiplication, and division by changes in state- ments 3000 through 3080. The pro- gram does its job on large numbers in the same way hand arithmetic; that is, it operates on one digit at a time, then carries to the next, and so on. This particular listing is long and slow, because we wanted to make it clear and easy to read so that you could see what’s happening. You may modify it to run much faster. Incidentally, you can get a better understanding of the pro- gram’s operation by relating certain of its statements to the ASCII con- version table that is in this issue’s OUT OF THE MIST section. State- ments 2500 through 2520, for example, result in the keyboard. being read directly. 2540 refers to CHAR = 141; reference to the table tells you that decimal 141 is actually the Carriage Return. Similarly, 2545 excludes all charac- ters except for the digits 0 through 9 (176 through 185). Again, state- ment 2550 converts the ASCII characters to the numbers them- selves (i.e., if CHAR = 181, then 181-176 = 5). we do it by long- ne svNrax ERR 10 REM MULTIPLE PRECISION ARITHMETIC 20 REM AN INTEGER BASIC EXAMPLE 30 REN THAT PROVIDES 20-DIGIT 40 REM 100 Gos 200 GOSUS GETA REM GET FIRST NUM 300 GOSUB GET®.
