Hi,
I got this system dump out in the middle of an assembly program that refers to a branch instruction (code snippet is available at the end of the post).
Here is the error :
| Code: |
IEA995I SYMPTOM DUMP OUTPUT 411
SYSTEM COMPLETION CODE=0C1 REASON CODE=00000001

END OF SYMPTOM DUMP |
and the code is :
| Code: |
C 2,=F'0'
BE FIN
...
...
FIN ...

Thanks for your time and consideration |

It shows that your original BE FIN instruction has been overridden with zeroes: X’00000000’ - somehow, before your program has reached this point.
BTW: ABEND S0C1 means “invalid instruction code”, which is X’00’ in this case.
The location pointed by PSW:
X’5920C18A’ - seems to be C 2,=F’0’
X’00000000’ - former BE FIN, now erased
X’41400002’ - seems to be LA 4,2
(if only I still remember the instruction codes...)
Check, or trace the logic of your code. |

| DO NOT assume 5920C1BA is an instruction. It may be the last 4 bytes of a 6 byte instruction |

Based on PSW, and R12, and instruction code + operands, the probability is 99.5%
Especially if the next instruction after BE FIN is really LA 4,2 - then I’m 100% sure. |
