Perhaps you could add a 64 right after the 6C for more effects?

Alternatively, you could use
FA 10 And Immediate with 10
32 xx Jump if Zero
This would save you 2 bytes (4 machine cycles), not that it
really matters but more for getting you thinking. I use just
one shift, that saves me 1 byte (which I really need because
I crammed this routine into a small free spot in my RS-232
monitor program). Two shifts, and you're breaking even
with the "And Immediate" solution.

I suggest you look back on the messages and find
the thread about Calling Subroutines.

This is only a hobby for the most part, right?
PS. I've not done any work with the Z8. The processors
I've done a lot of work on are 68HC11, 8051, PIC16x, PIC12x.
Some work on 8085, 8088, Z80, 6809
