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

       /PAGE[=lines-per-page]

    Specifies the number of print lines between perforations for
    hardcopy terminals. (When the terminal reads a form feed, it
    advances the paper to the next perforation.) The value of the
    lines-per-page parameter can be from 0 to 255 and defaults to 0
    (which treats a form feed as a line feed).
