All:
I just made a really dumb mistake which proved hard to debug. I was trying to call a function named ReadSelectButtonPress(), which returns an integer value using the call:
?? val = ReadSelectButtonPress;
It was not behaving as expected so I placed some scaffolding print statements in the function, recompiled, ran the code but never saw the debug prints. Clean compile, so errors.
It's one of those flat-forehead mistakes. I left the function's parentheses off the calling statement. I'm not positive, but looking at the number I was seeing for val, I think the code assigns the lvalue for the function into val. If it were really behaving like a pointer to function, it would have executed the function code.
I'd be embarrassed to tell you how long I spent chasing this bug... -- Jack, W8TEE
