Re: A86: Re: on-calc programming
I have both z80 books from Zilog. I also found an op list at ticalc.org. I
can't even get a simple program to run though. I type in:
:AsmPrgm
:CD7E
:4AC9
which should call (CD) clear screen (4A7E) then ret (C9). I know the call
has to be flipped (anyone know why?), but I keep getting syntax errors when
I run/AsmComp it. what's up?
