                           BE CLS (Clear Screen) 
 
Description:   Sets the background color to black, erases the screen, and
               then resets the original background color. 
 
Syntax:        Version 4.5:   BE CLS 
 
                                    Note:

The DOS CLS (clear screen) command erases only the characters displayed on
the screen, leaving the background color unaffected. When BE CLS is used, it
sets the background color to black before erasing the screen; this might be
useful for subsequent BE BOX or BE ROWCOL displays. If you subsequently use a
DOS command such as ECHO or TYPE to display data, the data appears in the
original foreground and background colors.
