Thread Subject: Aborting a function politely

Hi everybody,
I know the "error" call that can abort a function call and jump back to the prompt level. This function writes on the command window a "red message" that some users could consider "ugly" and not particularly user friendly.

Is there some way to jump to prompt level, aborting all levels of nested function calls, writing out something in "normal" format, or maybe writing nothing at all (I could always use a msgbox call to explain the abrupt stop).

I need this for the case of fatal errors (missing files, completely wrong user input, and so on).

Thanks a lot & best regards
Claudio

There have been some posts here concerning returning from deeply nested functions. But in your case of fatal errors, I think and warning in red color is absolutely appropriate.

You can suppress the display of warnings by encapsulating the calls in a TRY-CATCH-END block. The in the CATCH you can dispaly the error message in black (as usual) and return to the prompt eith RETURN.

Good luck, Jan
