AIB return and reason codes set by IMS

When certain events occur during DL/I processing, the IMS system issues return and reason codes. These codes are returned in the application interface block (AIB) when you use the AIB interface.

Important: X'000000F0' is a unique AIB return code assigned to the IMS Queue Control Facility manager message requeuer processor (IQCQMRQ0). It is set in the AIBRETRN field of the AIB by IQCQMRQ0 when an error is detected while performing an IMS Queue Control Facility function. For information about AIB reason codes that are associated with AIB return code X'000000F0', see the AIB reason codes information.
