Hi,
Did anyone have to change existing Cobol, CICS or JCL when you migrated to z/OS V2R2? I checked the IBM Knowledge Center for the new features and I did not see anything that would impact the existing code base.
Thanks,
Dexter |

Do you have any HLL (such as COBOL) traversing control blocks using hard-coded offsets? These will definitely be an issue if these offsets have changed in the z/OS control blocks.
Assembler traversing control blocks should be OK as long as you're not using hard-coded offsets, but rather, the associated DSECTS.
Is your CICS Version/Release supported for z/OS V2R2?
Compatibilities can be cumbersome.
Welcome to the forum....

If you go to Enterprise COBOL 5 or 6 with z/OS 2.2, the use of PDSE instead of PDS will be required for the load library. |

Thank you, Mr. Bill.
I have not encountered hard-coded offsets used by control blocks but will check our libraries to be sure. We are running CICS 5 so I beleive it is supported by V2R2.
Cheers!

Hi Robert,
You're right. Somehow I missed that when I went through the software requirements and v2r2 documentation. Fortunately, our datacenter may have prepared ahead because our load libraries are PDSE (DSN Type = LIBRARY). I'll check other libraries used in our system if they are also in PDSE. Much appreciated.
Cheers!
