Error description
Ø The failing instruction for the ABENDS0C4 PIC10 is 4430 C1E6. The problem is that the PSW is in KEY7, but Reg12, which points to CSQMNCPY+0 is in KEY0. The ABEND0C4 occurs in CSQMNCPY when MQOO_RESOLVE_LOCAL_Q/TOPIC is specified when opening a topic object. CSQMTOPN locates the address of the name of the topic object, which is in 64-bit storage, but it only passes a 31-bit address (i.e. low word) to CSQMNCPY for copying the name of the object back to the MQOD. Additional Symptom(s) Search Keyword(s): ABEND5C6 5C6 00E7014F in CSQXADPM may be a secondary symptom after the ABEND0C4.
