by Steve Wozniak Apple Computer, Inc.(Reprinted from Dr. Dobbs Journal of Computer Calisthenics and Orhtodontia, Box E, Menlo Park, Ca. 94025, Issue No. 23) An understanding of the internal representation of a BASIC program is necessary in order to develop RENUMBER and APPEND algorithms. Fig. 1 illustrate s the significant pointers for a program in memory. Variable and symbol table assignment begins at the location whose address is contained in the pointer LOMEM ($4A and $4B where ‘$’ , stands…
To set HIMEM at locations above 32767, use minus figures, i.e., HIMEM (-32767-1) would set it at 32768; -32766 sets 32770 .
For a limited time only, Computerland Federal Way has sets of Apple 16K chips available to members. This is a rare oportunity to get these chips for just $300.00, which is about 40% off the Apple list price. Call Max Cook at 206-838-9363 for details.
Don Williams will be our instructor for an 18 hour Assembly Language programming course. The cost is $35, which includes the Synertek 6502 Programming manual, and will be taught two nights per week at Empire Electronics, 616 SW 152nd St. , Burien, starting in the early part of May, so time is short. Contact Don at (206)242-6807 or Tom Geer at (206)244-5200 to sign up.
Sometimes the problem is not what to write about, but what not to write about. Such is the case this month when we have a large number of items to report. Our software library is first on the agenda. The library, along with the membership, has been growing by leaps and bounds. So much so that by the time a catalogue is issued, it is out of date. We will try to remedy this by listing new programs each month…
For those who have missed the last two A.P.P.L.E. Members meetings, Annual dues for the group have been established. Dues for 1978 will be $4.00 USD and are payable now.
I would like to comment briefly on my. experience running Don’ s program the first time. Like most of you, I have had very little to do with low level programming. With Don’s program, I was able to see at a glance how a BASIC line like “500 PRINT” translated into Hex bytes 08 F4 01 63 01, and in turn, I was able enter a line of Basic from machine language. Examining the result, I was able to determine…

A collection of tidbits worth nothing What is a color monitor worth to you? One of our number has access to same and will consider all serious offers… If you want 16K chips, tell us. We would have to buy a large quantity, true, but we have to know how many we can handle before we approach a manufacturer. We feel we could do something for under $250. Speak now or forever hold your chips. We have to get moving…
This month, we have a number of brief programming aids. For starters, here is how you can break your long PRINT statements in pages:For more than two pages, use this subroutine, inserting the GOSUB after 20 or less lines: 200 VTAB 22:PRINT “HIT RETURN FOR NEW PAGE”: CALL -676: CALL 936: RETURN. This will halt the program with a bell, and wait for a Return to resume. To correct a line in a program listing, POKE __, 33 before listing….
21 March 1978Time: 1905Place: Burien Empire Electronics The meeting was held at Empire Electronics in Burien.

They were made in Canada and designed for use in pubs and arcades. There…

As stated elsewhere in this issue, Apple Computer plans a new edition of Applesoft on tape about six weeks hence. They have requested that users advise them as soon as possible of any bugs they have encountered. This goes for Integer Basic, as well. This is a project in which EVERYONE can contribute. LET’S DO IT NOW, at this coming meeting. Make a list out, as soon as you read this, any basic bugs you are aware of, and bring…
February 1978 MeetingDate: 21 February 1978Time: 7pmLocation: Computerland Federal Way Minutes: We met at Computerland in Federal Way, and Val Golding called us to order at 7:05 PM. A motion was approved to call ourselves A P.P.L.E., standing for Apple Pugetsound Program Library Exchange. Val was unanimously elected president and Mike Thyng was elected Secretary. Other duties will be shared between them. Informality was stressed in the meeting, in order to best follow the purposes of the group: to exchange…
As we indicated last month, we need your software for our library, in order to make it available to others. You can help cut down on our processing time by observing the following guidelines. All programs should be completely self-prompting. This means all user instructions should be embedded within the program as “print” statements, so the user can run the program Without any additional information at all. Please state the language the program is written in, i. e., Integer BASIC,…
