The APPL statement

A VTAM® APPL definition statement defines the VTAM options for the DB2® subsystem and includes it in a major node.

With VTAM, you can use a model application program definition for DB2. With a model definition, you use wild card characters for the application name (LU name).

Spiffy uses the statement in the table below for the USIBMSTODB21 DB2 subsystem:

For your convenience, the APPL statement example is provided in data set DSN8VTAM, in the sample library, SDSNSAMP.

The topics that follow describe the APPL options that Spiffy uses and a few more in which you might be interested. Not all APPL options are described.
