If there is an SQL statement in the CA Easytrieve application, always the same module names are being called.
But the modules themselves are not the same, because you have to concatenate the appropriate Pan/SQL load library in the EZTPA00 step.
There are different load libraries for the different Data Bases (DB2, CA Datacom/DB, Oracle etc.).
In the separate load libraries, many of the load module names are the same name, but not their sizes.
