How does push/pop relate time-wise to actually storing/retrieving from
memory. I was under the impression the push/pop was rather slow compared to
direct memory accessing, but I haven't programmed asm since 386 days (ahhh...
=) I'm just getting into it now and finding it quite fun, except I can't get
my code to debug under RHIDE at all. :-(
