Re: A82: Adding 100 (to score-asm)
Yes, its legal. However, a is an 8 bit register. Therefore, if you want a
9 bit score (say 300, your dead). This will work for much larger numbers:
ld hl, (score)
ld de, 100
add hl, de
ld hl, (score)
Make sure score is 16 bit. (bs1 = TEXTMEm, score=textmem+1,bs2=textmem+3)
