/sys$common/syshlp/helplib.hlb VIEW, Qualifiers, /OUTPUT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /OUTPUT=output-filename
       /NOOUTPUT (default)

    Specifies a file that you want to receive the output instead of
    having it displayed on the screen. You cannot use this qualifier
    when you have specified the /INTERFACE=DECWINDOWS qualifier.

    If you specify /OUTPUT but you do not specify a file name, the
    CDA Viewer creates a file with the same name as your input
    file but with a file type of LIS. If you specify the /OUTPUT
    qualifier, you cannot also specify the /PAGE qualifier.
