I'll assume it was the same in VFP 5 as it is today. SET NEXT STATEMENT is available only with the currently executing code module. Unfortunately you can't branch to a different one.

Make sure that every function, procedure, method has a RETURN statement, if it's just returning .T. Add the following code snippet at the end of your error handler to give you more control over debugging:

IF .F.
RETURN
RETRY
ENDIF

The code won't normally execute, of course, but you can use it to control how you proceed after your error handling. FWIW, I also always include and ASSERT statement in my error handler in addition to the normal user messages, error handling.
