AERCO Merge Function

Larry Zunk of Zunk Custom Electronics (4800 East Cedar lane, Norman, Oklahoma 73071), shares a few routines for the AERCO FD-68 disk drive system. Larry has programmed a powerful software package for the FD-68 called “CADZ” (watch for review in upcoming issue, or write to the above address for further details).

This is a tip for all Aerco FD-68 users. The basic MERGE function has never been available, but a simulated merge can be accomplished.

Rule #1: line numbers must be consecutive. Rule #2: get rid of all variables. Rule #3: is make sure there is enough room for both listings.

It works like this. In the immediate mode, type:

CAT "first program.BAS",
CLEAR 65535
POKE 23635,PEAK 23627          (POKE prog,vars)
POKE 23636,PEAK 23628
CAT "second program.BAS",

(NOTE: Execution will stop here, and all you will see is the second listing.) Then also in the immediate mode, type:

POKE 23635,86
POKE 23636,104                 (POKE prog,26710)
