Re: A82: Copying HL -> DE skipping bytes
Firstly, I'm pretty sure what you actually want to do is copy a bunch of
memory pointed to by hl to the address stored in de, not store h in d as
your statement implies. Secondly, if you're trying to do something like
this:
hl-> 1,2,3,4,5
de-> 1,x,2,x,3,x,4,x,5
then your code (both versions, since they do the same thing... the second
is better, though can be further optimized, slightly) works fine.
