How to Resume Processing

If you determine that processing can continue, you can resume at the current resume cursor location. Before you can resume processing, the exception message must be changed to indicate that it has been handled. Certain types of handlers require you to explicitly change the exception message to indicate that the message has been handled. For other handler types, the system can change the exception message before your handler is called.

For a direct monitor handler, you may specify an action to be taken for the exception message. That action may be to call the handler, to handle the exception before calling the handler, or to handle the exception and resume the program. If the action is just to call the handler, you can still handle the exception by using the Change Exception Message (QMHCHGEM) API or the bindable API CEE4HC (Handle Condition). You can change the resume point within a direct monitor handler by using the Move Resume Cursor (CEEMRCR) bindable API. After making these changes, you continue processing by returning from your exception handler.

For an ILE condition handler, you continue the processing by setting a return code value and returning to the system. For information about actual return code values for the Register a User-Written Condition Handler (CEEHDLR) bindable API, see the API topic collection in the Programming category of the IBM® i Information Center.

For an HLL-specific handler, the exception message is changed to indicate that it has been handled before your handler is called. To determine whether you can modify the resume cursor from an HLL-specific handler, refer to your ILE HLL programmer’s guide.
