 |
|
| I am trying to get a COBOL XML parser to work but it is failing at run-time because it can't locate module IGZCXML. Can anyone tell me where this module is located? |

Kolusu,
I am running Enterprise COBOL 3.3.1 and this APAR relates to 3.1 which is when it was added. I checked SCEERUN and SCEELKED but it not in either. Do you know which library I should look in? |

Bithead,
I did not find the module IGZCXML at all and I am running only Enterprise COBOL for z/OS and OS/390 3.2.0. Try to run this JCL and see if it works for you.

Kolusu,
I think that this refers to OO COBOL access JVM parameters. The IBM sample is not OO so I don't see how this would fix the problem. We are not running Java on our mainframe.

Bithead,
The apar also listed the macro IGZCXML in it. I thought it might be related. Can you post the complete error messages?
I just looked at the load-module of my pgm and I don't find any IGZCXML modules at all. I can only find references to IGZCBSO.

Bithead,
After a bit digging I found that IGZCXML is actually a CSECT in the load module IGZCPAC which can be found in SYS1.SCEERUN.
Hope this helps...
Cheers
Kolusu

Bithead,
Did you look at the load module IGZCPAC in SYS1.SCEERUN?

| There is a CSECT called IGZCXMU but that's all. I have found an allocation for SCEEXML in SCEESAMP(CEEWALOC). Do you have this library? |

Bithead,
I also see an allocation for SCEEXML in SCEESAMP(CEEWALOC). I ran an amblist on IGZCPAC and found that IGZCXML is loaded as a part of the PTF UQ85364 which was found on this page
http://www-1.ibm.com/support/docview.wss?uid=isg1PQ80358
| Code: |
IGZCXML SD 02DC8 E50 HLASM 04/02/27
IDENT 04/11/20 UQ85364
IGZCXMU SD 5EC68 3E1 HLASM 02/04/05
IDENT 02/04/05 RSI20952486
|
Also check this link for Table of compiler maintenance levels required for Debug Tool
http://www-1.ibm.com/support/docview.wss?uid=swg21180142
PTF UQ85364 was a part of Language Environment PTFs for Enterprise COBOL for z/OS runtime support
Hope this helps...
Cheers

Thanks Kolusu, I will take a look at the APAR.
We don't use Debug Tool so we should be all set there. |
