I once used a disassembler (I can't remember for what CPU) that would
put a comment on each line giving the ascii character equivalents of the
So you would get something like (totally ficticious instruction set) :
0100 48 65 6C ST R8 (656C) ; Hel
You (the user) could then decide if the instruction or text made more
sense. Of course it didn't help with, say floating point numbers, or RAD50
