Where is NOP on the HP-67 ?

Looking at your code, in all three cases where the NOP appears it does it after a test which executes a RTN if true, so the NOP is never executed and you can safely replace it with another RTN, like this:

g X#Y?
RTN
RTN

V.

Thanks, I'm trying but it doesn't run, it shows error at any label key pressed
How do you code LBL A in an HP 67 ? f LBL A ? or just pressing A ?
