On Error Statement diagram


On [Local] Error {GoTo Labelname | GoTo 0 | Resume Next}

Parameetrid:

GoTo Labelname: lubab vea ilmnemisel veahalduse alamprotseduuri, mis käivitatakse real "Labelname".

Resume Next: vea korral jätkatakse programmi käitamist lausega, mis järgneb lausele, kus viga ilmnes.

GoTo 0: keelab veahalduse aktiivses protseduuris.

Local: Optional. The keyword is a reminder the statement is local to the routine which invokes it; when the routine exits, this error handling is canceled automatically.

Näide:
