RetIfZ

Tests contents of X and Pop's stack. Then, if X was zero (or False), returns program flow to the line following the most recently executed GoSub instruction.

If a return is attempted when there was no matching GoSub, the SPLat development environment reports an error and the SPLat hardware resets.

This instruction has the alias (alternative name) RetIfF
