RC = 12 REASON = R15-CATALOGENTRYMGR SUBREAS = 0	Error accessing CATENTRY.
RC = 12 REASON = 98-CATALOGENTRYMGR SUBREAS = Bytes 1,2- catalog module identifier Byte 3-Internal REASON, Byte 4- Internal RC.	Error accessing CATENTRY.
RC = 16 REASON = R15-GETMAIN or FREEMAIN SUBREAS = Byte 1-internal Byte 2-0 Bytes 3 and 4, X'78' or X'05'	Processing error (GETMAIN or FREEMAIN).
RC = 32 REASON = 0 SUBREAS = 0	Parm list error.
RC = 64 REASON = 0 SUBREAS = 0	Major Error (ABEND).
RC = 900 REASON = 0 SUBREAS = 0	An abend occurred.
