You'd get that in IDE, when "available" is "is mentioned on the stack or in set procedure". In an exe, whatever is in the project, exists. So you'd not get that result in runtime, and would have to go back to thinking it over.

Yup, the test as it is now is more to the point - you are testing for a real clue as to whether the thing was set or not, i.e. the thing itself. The "do I have this function" test is obviously giving you wrong results (nonexistent before set procedure in IDE, always existent in exe).
