Coding the APPL definition statement

The VERIFY parameter on the application program's APPL definition statement indicates the degree of Level 1 session-level verification it requires.

The valid values on the VERIFY parameter are:
NONE
The application program does not support session-level verification. Sessions with this LU will not be activated using session-level verification.
OPTIONAL
If a session key is defined in the LU-pair profile, all sessions between the LU-LU pair must be activated using session level verification. If no session key is defined in the LU-LU pair profile, sessions between the LU-LU pair are not activated using session-level verification.
REQUIRED
All sessions with this LU must be activated using session level verification.
