 |
|
Hi all,
I encountered Abend U4088 Reason code=7A in CICS for the below secanrio,
Program A links to Program B:
Program A:
--------------
WORKING-STORAGE.
01 WS-PASS-DATA PIC X(100).
PROCEDURE DIVISION.
............
EXEC CICS LINK PROGRAM('B') COMMAREA(WS-PASS-DATA)
LENGTH(LENGTH OF WS-PASS-DATA) END-EXEC
Program B:
---------------
LINKAGE SECTION.
01 DFHCOMMAREA.
05 WS-GET-DATA PIC X(100).
05 WS-REQUEST-TYPE REDEFINES WS-GET-DATA PIC 9(04).
Program B fails with abend Abend 4088 and also triggers a stroage violation.
I was advised that REDEFINES clause should not be used in the COMMAREA and it is the cause for the abend.
Is this theory correct ? If yes why is it ?
Please advise. |

Nothing wrong with that..... | Quote: | | Program B fails with abend Abend 4088 and also triggers a stroage violation. |
Have to lookup the 4088, but reference to the commarea should not be the storage violation.... | Quote: | | I was advised that REDEFINES clause should not be used in the COMMAREA and it is the cause for the abend. |
Balderdash! | Quote: | Is this theory correct ? If yes why is it ?

No, it is not correct..... |

Thank you for the quick response.
The explanation for the abend 4088 says that, Stack pointer corrupted and Stack overflow.
What are the possible programming errors that cause the abend 4088 ?
And how to debug this abend ?
Thanks in advance. |

Sounds like a storage violation..... | Quote: | | What are the possible programming errors that cause the abend 4088 ? |
subscript/index range checking might help.... | Quote: | | And how to debug this abend ? |
Ah, now that's the hard part....The first place I'd start is to get a dump of the corrupted storage, look for fingerprints of what kind of data landed there - That might help to point back to the offender....
Also look at the storage adjacent to the corrupted storage and investigate the program logic that accesses and stores in those surrounding areas... |

knallathambi,
Are there any Getmains that you used? .. It is quite possible that the length of getmain that you did was not sufficient.
