CICS VSAM Transparency for z/OS, Version 1.2


Changing existing VSAM calls

Each CICS® VT DDM driver module contains all of the SQL to simulate every possible VSAM call. This means that you can change any existing calls in an application program without affecting CICS VT. You can also add new VSAM calls to an existing program without affecting CICS VT.

As an alternative to changing an existing VSAM call, you could consider replacing it with an equivalent SQL call. This allows you to use the full functionality of SQL. You can also add a new VSAM call to an existing application program.

No CICS VT actions are required in these situations.
