    PGFORM [linelength [pagelength [pageoffset [1]]]]
        Set line length, page length, and/or page offset.  This macro
        can be used for special formatting, like letter heads and other.
        It is normally the first command in a file, though it is not
        necessary.  PGFORM can be used without arguments to reset
        everything after a MOVE call.  A line break is done unless the
        fourth argument is given.  This can be used to avoid the page
        number on the first page while setting new width and length.
        (It seems as if this macro sometimes doesn't work too well.  Use
        the command line arguments to change line length, page length,
        and page offset instead.)
    Number variables used in mm
        W      Line length, only for command line settings.

Cheers, Ralph.
