The installation can print those data using the Environmental Record Editing and Printing Program (EREP) service aid or the stand-alone version SEREP. The MCH can handle memory failures in refreshable nucleus control sections by reading a fresh copy from SYS1.ASRLIB and can handle memory errors in SVC transient areas by reading a fresh copy of ...
