Specifies that a logical port on your local node is dedicated
    to an application service. The /DEDICATED qualifier requires the
    /SERVICE qualifier.

    To set up an application service for a logical port on a LAT
    service node:

    1. Create the service by specifying the CREATE SERVICE
       /APPLICATION command and then define the dedicated port by
       specifying the CREATE PORT/DEDICATED command. You can include
       these commands in LAT$SYSTARTUP.COM.

    2. Associate the dedicated ports with the service by specifying
       the SET PORT/DEDICATED/SERVICE command.

    3. Start the application program. Within the program, allocate
       dedicated ports with the same name as those defined in
       LAT$SYSTARTUP.COM.
