MDLTAB

Specifies the name of the model name table to be used for the logical unit. See Model name table for a description of how to define a model name table.

The model name is passed only when VTAM® initiates the session with the application program, for example, only when the LOGAPPL = parameter is also coded.

If you omit the LOGAPPL operand or the MDLTAB operand, VTAM will not provide the name of the model name table to the application during LU-LU session initiation. However, you can provide the model name in other ways. You can enter it from the terminal on the MODEL operand of the LOGON command, or VTAM can send it to the application in a formatted session-initiation request. See LOGON command for more information on the MODEL operand of the LOGON command.

You can use the MODIFY TABLE command to dynamically replace a model name table. See z/OS Communications Server: SNA Operation for more information about the MODIFY TABLE command.
