VMS Help SET, ENTRY, Qualifiers, /TRAILER  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /TRAILER
       /NOTRAILER

    Controls whether a trailer page is printed at the end of each
    file in a print job. The trailer page displays the entry number,
    as well as information about the user submitting the job and the
    files being printed.

    When you use the /TRAILER qualifier with the SET ENTRY command,
    trailer pages are placed at the end of each file in a multifile
    job.

    Use the /[NO]TRAILER qualifier to override the installation-
    defined defaults that have been set for the output queue you are
    using or the qualifier specified in the PRINT command that queued
    the job.
