  Argument
 
    count    _GScrollUp, _GScrollDown, or number of lines to scroll
 
  Description
 
    The _ScrollTextWindow procedure allows you to scroll the text
    window (defined by _SetTextWindow) up or down any specified number
    of lines. A positive number scrolls the window up (the normal
    direction), while a negative number scrolls the window down.
    The constants _GScrollUp and _GScrollDown scroll the window up or
    down one line. The arguments for _ScrollTextWindow can be an
    expression such as _ScrollTextWindow( _GScrollUp * 8 ). Specifying
    a number larger than the height of the current text window is
    equivalent to calling the procedure _ClearScreen( _GWindow ).
    Specifying 0 causes no action.
