Solution:

No, not directly within the VTAMLST member.

At startup, TPX must know about every possible virtual terminal used in order to allocate control structures for them.

As of TPX 5.2, you can use TPX batch with VTAM modeling statements to generate your VTAM APPL definitions. This is described in the TPX Batch Administration Guide and allows for the use of wildcards. (See chapter: Using VTAM Modeling Statements.)

TPX 5.3 introduced the ability to use OS symbols within the modeling statements.

With the appropriate use of OS symbols and wildcards, it is conceivable that you can use one set of modeling statements to generate the VTAM APPLs for all of the different LPARs and TPXs that you need.
