Overview

To code a model application program definition, code an APPL definition statement to define application program characteristics that you expect to be used by one or more VTAM® application programs. Use wildcard characters in the name field of the APPL definition statement. You can use the following characters:

Asterisk (*): Represents 0 or more unspecified characters.
Question mark (?): Represents a single unspecified character.

When placing wildcard characters in the name fields of model application program definitions, you should have some idea of which dynamic application programs might be built from those model definitions. You will probably want to use a naming scheme that ensures that dynamic application programs are not accidentally built from model application program definitions; that is, that an application program does not open its ACB using a model definition that you did not intend for it to use. See Table 1 for examples of model application program definition names and the names of the dynamic application programs that could be built from them.
