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

    /PAGE (default for screen display)
    /NOPAGE

    Displays terminal output one screen at a time. The page length
    is automatically set to 1 line less than the value specified
    by SET TERMINAL/PAGE. (Use of /PAGE is incompatible with
    /OUTPUT=filespec.)
