But from that what I read (or undestood) Chaim wants to raise error 39, not to handle it. May be I am wrong.

>>>Hi
>>>Can I tell vfp: when you want to give me the error message 'Numeric overflow' (error 39), fill the field with 0 (in all of the code without adding the line if between(field.value,-9999,99999999) for each case).
