Bytes From The Apple

Bytes from the Apple

As usual, we are down to the wire again as it comes time to write this column. We are still receiving applications from all over the country as we pass the 110 mark in membership, and we would also at this time like to extend a special welcome to our first overseas member, Paul Moortgat who lives in Nieuwkerken, Belgium! There are many special features for new members in this issue, and we would like to refer you to the “In This Issue” column on this same page.

Many new programs have been received in the last two weeks, and more are on the way. They will all be made available through our library at the earliest possible moment.

This is a good time and place to mention that we need YOUR original programs. Not only do we need them for the library, but we also have obligations now to other groups and individuals who have furnished us with programs. Should we introduce a “Letters” column? Because we have members now scattered in just about every part of the country, phone calls are a bit on the expensive side. We certainlywelcome your questions, either on the Call -Apple “hotline” (206) 932-6588 or by mail. Marvin Eidinger in Pullman Wa. has written to ask, among other things, how the “save” routine (page 40, red manual) works, and how is the append routine to be used. We would like to answer both questions here. The data save routine will write to tape all of the variable data stored between the LOMEM: pointers 74& 75 and the variable pointers, 204&205. APPEND, which is a routine within our PROGRAMMERS WORKSHOP program is designed to join together two or more individual programs to form a whole. This is what we use when we take a number of programs & put them together on a menu in the form of one of our Game Paks. Its most useful function, however, is appending a program on to the workshop so that the program may be examined and modified, using many of the different Workshop routines. It is also a good learning tool, to aid you in learning hex and in general, more about how your Apple II functions.

A final note for this month, als0 with regard to learning. USE YOUR RED MANUAL! There is an entire world of information contained therein. You don’t need to know assembly language, although it is, of course, although it is helpful. READ and STUDY the monitor listings. Find out what they do. USE them. They can all be called from Basic. Convert the hex addresses to decimal. If > than 32767, subtract from 65536 to get the negative value and CALL them. Remember, you can only blow a program, not your monitor.
