A86: Re: 3 questions




I can only answer one of your questions.  I assume you mean subtracting b
from a temp variable, but I could be wrong.  Here it is.

    ld a,b                ;load b into the accumulator
    sub (variable) ;subtract the variabl from the original number
    ld b,a                ;this returns the value to b

variable:               ;this is the temp variable
    .db 0
