When control returns to the caller from a PROCESSMULT request, the request is complete and the result of its completion is indicated by the return and reason codes in RETCODE and RSNCODE. The PROCESSMULT request might have completed fully or partially, depending on whether all the LRBs in the buffer area were processed. The number of LRBs processed is returned in REQPROC when the PrOCESSMULT request completes synchronously.
