Re: A86: HI.
_asapvar is the name of the asm program being executed (in op format). This
can be useful for writeback, and also to force the calc to recopy the program
since it doesn't bother recopying if you execute the same prog from asm(
twice in a row. You can force a recopy like this:
xor a
ld (_asapvar+1),a ;length of name=0
However, I wouldn't recommend using the above code and later in the program
referring to _asapvar in the writeback routine :P
