A specific error-handling logic can be implemented based on To enable the RPG error indicator handler, you specify an error indicator in positions any operation that supports it. To handle errors, you can specify a monitor group within an on-exception block. If an exception occurs on the operation, the indicator is set on, the appropriate data · If an 'E' operation code extender is present on the calculation specification and error indicator is not present then the error occurred will be handled by this operator extender ‘E’. Some are straightforward, but many are cryptic, This means that a *PSSR in a main procedure will handle only those program errors associated with the main procedure.
