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

       /HEIGHT=nn

    Specifies the height of the page in number of characters. If
    you specify the /OVERRIDE_FORMAT qualifier, or if the document
    being viewed has no inherent format, this page height is used.
    On the DECwindows Motif display, the default height is 66 lines,
    which is equivalent to the default page height of 11 inches.
    On character cell displays, the page height defaults to your
    terminal's screen height. However, if you use the /OUTPUT
    qualifier, the page height depends on the page height of your
    document.
