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

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 ?


In an HP-67 it's indeed f LBL A, but I think that just A in the HP-65 might mean the equivalent of the HP-67's instruction GSB A, not LBL A.

I don't own an HP-65 but I understood that a test would either execute or skip two steps so the above sequence would mean that either both RTN are skipped or the first one is executed, so the second one never is.

As you get an error, I'll step aside and let HP-65 owners take over.

Regards.
