OK, I might be going for The Worst Question Ever Asked on ASM83 (tm), but I need to know the following:
 
how can you check if a number is larger than another (I only need to know how to do this with 8 bit numbers.)? Is there a way to load the 1st number in the accumulator and cp/and/or/xor/rr/slr/sla/rl it with another number to do this?
 
Please let me know...
 
Frank
