/WIDTH=nn

    Specifies the number of characters per line. If you specify the
    /OVERRIDE_FORMAT qualifier, or if the document being viewed has
    no inherent format, this page width is used. On the DECwindows
    Motif display, the default width is 85 characters, which is
    equivalent to the default page width of 8.5 inches. On character
    cell displays, the page width defaults to your terminal's screen
    width. However, if you use the /OUTPUT qualifier, the default is
    132 columns.
