Re: A86: ASM Programming Test - div 3
A little loop like I had isn't very big, and what you had seemed like it
would take up alot of space (at least 3-4 times as much, and like you said,
it's more like 12-13). For what I am using it for, I'm dividing map coords
that have a range of 0-63 by 3 to fit into a radar display, so it would loop
1-20 times. Not bad at all, imho. If you were routinely dividing numbers
that were > 128, it might be worth it. For small numbers, I'd say forget it
(though you are welcome to try).
