To be position-independent or deterministic, you don't need DAA to do the
conversion. The following suffices, and I'm sure that I could do much
better with a little head scratching:
and al,15
sub al,0a
mov ah,al
not ah
shr ah,5 (if on 8088, you can substitute 5 shr ah,1)
add ah,3a
add al.ah
Code-cruncher quiz: Could this be done in 8088 code without DAA or a jump
or a reference to a table in memory using only a single 8-bit register?
Cheers,
