hello,
Thanks again for everyone's help and answering my questions, as I struggle
through my project.. can someone tell me how to subtract two 16 bit vars?  I
tried:

ld hl,(var)
ld de,-(cash)
add hl,de		;but SCabBy said it wouldn't work

he said do

ld hl,(var)
ld de,(cash)
or a
sbc hl,de
ld (var),hl

i tried that, didn't seem to work.. is this right, or did i do something
wrong, or maybe I didn't interpret right?  Please help.  Thanks.
						-Ahmed
