A86: Re: on-calc programming




The Z80 reference book that I have lists all the opcodes and their binary
equivalents.  Try getting a reference book.

I tried programming like that before and it's very hard =).  If you ever use
a CALL, JP, or JR you have to remember to change the addresses they jump to
if you ever shuffle your code around.  If you try to stick with JR's then
individual code blocks won't be affected every time you add an instruction
somewhere else.  Also, the NOP instruction becomes VERY useful when
programming like this!  Have fun and be careful =).
