Each lock request block is processed in the order in which it appears in the REQBUFFER area. If the system encounters an error while processing a resource request associated with a lock request block, processing for that request is halted with the appropriate return and reason codes and the system continues to the next LRB. If the system encounters an error attempting to access the next LRB, the entire PROCESSMULT request is halted.

If you specified the REQPROC keyword, the system returns in that area the number of lock request blocks that were processed before the PROCESSMULT request was halted when the request completes synchronously.
