cany anyone tell me what 'opsyn' is used for? it seems to me that a way to
redefine (or undefine) standard opcodes would create maintenance problems.
what benefit is provided that offsets the risk? i myself have never seen
'opsyn' used anywhere, but i am not primarily an assembler programmer.
thanks, bob concannon, university of alaska, fairbanks
