Our customer wants know if they compile a COBOL CICS program in development environment with CA Datacom/DB v15, it will work fine in production environment with CA Datacom/DB v14?
Note: They only compile in development environment and use this object in production environment. 
z/os, CA Datacom/DB mixed release in Prod and Dev 
It is OK,
as long as the developer does not use new 15.0/15.1 functionalities which will NOT work (or give unpredictable result) in the CA Datacom/DB 14.0 environment.
