An error occurred while module IATSIDM (USAM subsystem interface routine) was attempting to open a SYSOUT data set. The FRR routine IATDMFR requests an SVC dump. IATDMFR returns to IATSIDM via the retry address (RETADDR parameter) on the SETRP macro. IATSIDM ends the job with a 1FB system abend code. The areas dumped are SQA, CSA, and LPA.
