    Hi,

    I'm trawling through some ASM code I need to update (not written by me) and having trouble interpretting some of it...

    LD {eval1+1},A

    Load acumulator to eval1... what does the +1 bit do? Is this to address the MSB, LSB?

    For instance if you define a word in memory, eg. eval DS.W 1

    LD {eval1+1},A would write to the low byte

    LD {eval1},A would write to the high byte.

    This is if MOTOROLA (Big endian) has been defined, if using INTEL (little endian) then the opposite applys.

    Regards
