VMS Help DEFINE, /FORM, Qualifiers, /SETUP  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /SETUP=(module[,...])

    Specifies one or more modules that set up the device at the start
    of each file. The modules are located in the device control
    library. While the form is mounted, the system extracts the
    specified module and copies it to the printer before each file
    is printed.

    For more information on device control modules, refer to the
    chapter on Batch and Print Operations in the OpenVMS System
    Manager's Manual.
