The Z80 had:
JR idx(unconditional)
JR Z,idx (jump relative if zero)
JR NZ,idx (jump relative if non-zero)
JR C,idx (jump relative if carry)
JR NC,idx (jump relative if non-carry)
And one of my favorites for loops:
DJNZ idx (decrement and jump relative if non-zero)
So, yes, the Z80 had conditional relative jumps. It also had that nice
set of secondary registers...very handy for interrupt processing.
Oh, no! You've started my "flashback" processor running. I'm not going to
get any work done today. Please stop. :-) :-)
