If the calculator returned x % 0 as x, then ignore my post. All is well ...

The program works fine for both 0 54 GCD or 54 0 GCD, returning 54 in both cases.

Friendly suggestion: Get an actual calculator (or install an emulator) and play along with the rest of us. It's the best way to learn RPL (or RPN, etc.)
