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

       /COPIES=n

    Specifies the number of copies to print. The value of n can be
    any number from 1 to 255. When you use the /COPIES qualifier
    with the SET ENTRY command, the number of copies can apply
    only to the entire print job. You cannot use this qualifier to
    specify different numbers of copies for individual files within a
    multifile job.
