Apple II Basic Structure

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…

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  So much so that by the time a catalogue is issued, it is out of date.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…

Don’s Translator

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…

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…

Bytes from the Apple

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….
