Data Statement Generator Virginia Lee Brady 0·3 Arthur Ct., Apt. 453 Salisbury, MO 21801 If you have ever had trouble getting those pesky DATA statements at the end of your BASIC program correct, then you will appreciate this program which "writes" its own DATA statements! Written for APPLESOFT, it should be adaptable to other BASICs.
"INPUT A$" 's, but using an array allows you to change a string before it is poked into memory). This is handled in lines 1035-1045. If there are no further changes, then the individual strings are concatenated into one long string with commas separating the individual substrings. Next this string is poked, one ASCII value at a time, into PSN + I + 2; then the "0" is poked into the end as the terminator.

~"\ Women and Chiidrenk,Lastl I have a feeling that the real "revolutionary" part of the microcomputer revolution is just starting to take place. Of course, parts have gotten smaller and cheaper; more software is available; new high level languages are coming along; and 50 forth. The real significance of all of these things lies, I believe, in the fact that millions of new people are going to get involved in computers and computing.

How to do a Shape Table Easily and Correctly! r ), John Figueras 65 Steele Road Victor, NY 14564 ·rhe mechanism for generating shapes and characters in APPLE High Reslution Graphics is cumbersome and prone to error. A very clear explanation of the mechanism and pitfalls is presented here. But, best of all, a program is presented which permits the user to create the shapes interactively, using the Keyboard and Display.
The ploting vector string is then broken up into groups of two or three, each group (confusion!) reading from right to left. To add a little more danger to the game, the rules require that no group of vectors may end with a move-up vector or with a plot-then-move vector, in which case the group will contain at most two plotting vectors. The table in Figure 3a shows how the above string is subdivided. In this case, because of the restrictions on termination, each group can contain only two vectors.

are to remain unchanged. This is done by multiplying V, by 8: BYTE = BYTE + 8"V, ~ OOYYYXXX Now for V,. To refresh your memory, you will observe in Figure 4 that all plot-thenmove 3-bit codes have their left-most bits "on." Since there are only two bits remaining unfilled in the byte, there is no way in which the plot status of the third 3-bit code can be entered into the byte. In this case, processing of the byte stops, and it is stored in the shape table, while V, is used to initialize the next byte.
any shape in the table. N, No. shapes Empty r Directory ) Byte 1 Byte 2 2* N Bytes The file initialization program is also used for creating the cursor required for mapping shapes on the 15 x 15 working grid produced by the principal program. This relieves the user of the need to generate the cursor himself every time he opens a new shape file. The cursor is stored as the first shape in the shape file, and the shapecreating program assumes that the cursor has already been stored for its use.
If the current keystroke corresponds not to a move command, but to a Plot command, the program sets the cursor disable flag, FLAG, calls the plot subroutine and then branches back to get the next keystroke (all of this is done in step 680). The Quit command forces a branch to a routine that closes out the current byte (starting at step 1080), adds a record mark (step 1170) and draws thew completed shape (step 1170).

Listing 1 o comes from bit 5 into bit 7. Since there does not exist an indirect addressing for the ASL command, I had to use the absolute indexed to increment the argument directly. Finally, TSCR throws the cells on the screen with 51 's if bit 7 is set and 20's (blanks) else. The RTS returns the control back to BASIC. For one generation the programs needs about 1/2 second. The speed may be slowed down by a waiting loop in BASIC.

KIM and SYM Format Cassette Tapes on APPLE II Steven M. Welch 309 S. Sunset Longmont, CO 80501 Now you can swap programs and data between your APPLE and any AIM, gYM or KIM via cassette 110. Many KIM and SYM owners have graduated to bigger and better 6502 systems" as their needs and financial situations changed. If you are one of these people, and find that your KIM is sitting in the corner gathering dust because your APPLE is so much easier to work with, read on.
;ng to my boss, Dr. Bruce Bohannan. The APPLE has almost all of the features of the typical Microprocessor Development System, except perhaps, a means of communicating with the SSC in question. How can an APPLE talk to a SYM? Fortunately, both computers use the 6502 micro-processor chip, so programs assembled for the APPLE have little or no trouble running on the SYM or KIM. Also fortunately, all of these machines have a means of reading and writing programs on audio cassettes.

APPLE II@.JOVSTICK & EXPANDA-PDRT EVERY APPLE II OWNER SHOULD HAVE ONE! ) The PROGRAMMA JOYSTICK is an input peripheral that attaches to the APPLE II Computer's game I/O Port. The JOYSTICK is a must for the serious game player, and it offers a degree of linearity not currently available with other joysticks. The ease of manueverability and the availability of the "functional" switches make the PROG RAMMA JOYSTICK a much needed enhancement to any APPLE II Computer System owner.

Computer Interfaces and Sets For your convenience the AIM16 comes as part of a number of sets. The minimum configuration for a usable system is the AIM16 Starter Set 1. This set includes one AIM16, one POW1, one ICON and one OCON. The AIM16 Starter Set 2 includes a MANMOD1 in place of the ICON. Both of these sets require that you have a hardware knowledge of your computer and of computer interfacing. . For simple plug compatible systems we also offer computer interfaces and sets for several home computers.

Graphics and the Chalienger1P William L. Taylor 246 Flora Road N.W. Leavittsburg, OH 44430 The Challenger computers have some interestings graphic capabilities. A discussion of the inner workings of the graphics and programs for using them are presented.. Introduction Recently I purchased an OSI Challenger C1 P, and I find its graphics and polled keyboard to be interesting tools for the programmer. But to the computer hobbyist with little experience in programming, it may seem very confusing.
video monitor screen, the ASCII equivalent must be written in the video memory. This memory occupies 1 kilobyte of memory dedicated to the video display. This memory is located at 0000 through 03FF hex, or 53379 to 54171 decimal. In the program I have set the video graphics pointer to point to mid-screen, as can be seen in the pro· gram at line 15. The mid-screen position is contained in the variable L. This is set to 53775 decimal.

line 1000. There is a subroutine for each of the least significant digit and a subroutine for the next most digit. To develope the digit 10, we must use two of the subroutines. This would also be the case for any number greater than 10. The program is separated by REM statements. Each module will begin with a REM statement that defines the function of the subroutine, and if the reader analyses each module he will get a clear picture of how the numbers are generated and placed on the monitor screen.

Here is a RAM memory test that can be adapted to any 6502 based system. ) SUMTEST is a short (107 byte) machine lang.uage program to test memory. The algorithm is not original with me, as I have seen similar routines published for the 8008, 8080, and 6800 microprocel!sors.
to be tested by adding the high order address and the low address of each location to a "counter" byte. After all locations to be tested have been filled with their calcuiated data byte, the routine then recalculates the data byte that should be stored in each location and checks it against the actual contents of the location. If the data in memory is different from the calculated value, then the location and offending bit pattern are printed.
