/SCROLL
       /NOSCROLL

    Determines how new lines of text are displayed on the screen
    when the viewport becomes full. If /NOSCROLL is specified, the
    text lines are wrapped and new text appears on the top line of
    the viewport. /NOSCROLL improves the response time for terminals
    operating at slow speeds.

    If /SCROLL is specified, the text is scrolled up one line each
    time a new line of text is entered. The new line appears at the
    bottom of the viewport. /SCROLL is the default.
