Umm, on a point of order...
I see what you're saying there, and neat trick! But...
pop B pulls a 16bit value off the stack into BC
pop A is (probably) going to be a syntax error. It would be "pop psw"
in Intel or "pop AF" in Z80 and anyway not what you want.
This isn't a 6809, you can't pop into (A,B). :-(
So what you want to say is...
[boring 8080 code]
call boo
boo pop b ; BC = address of boo
[more code]
Code in Assembly, and grow strong
