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. icon_smile.gif

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....

HTH....

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. icon_smile.gif

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!
Dexter
