In VFP you cannot use RETURN in a TRY/ENDTRY because it's not allowed there. See Structured Error Handling topic in the help for a list of commands than can/cannot be used in TRY/CATCH/FINALLY blocks.

Why it's not allowed is different question. Definitely it's not because of FINALLY block. Nothing would prevent VFP from executing FINALLY block before RETURN.

But I was wondering about the reason - just hoping to get a more profound understanding of the relevant aspects. So, why would VFP not allow the RETURN directly from the CATCH clause?
