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

       /FLAG
       /NOFLAG

    Controls whether a flag page is printed preceding each file in a
    print job. The flag page contains the name of the user submitting
    the job, the job entry number, and other information about the
    file being printed.

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