     USAGE
     
     Clear is used to clear the display and optionally set the
     colors of  the display.  It's parameters  are similar  to
     color. E.g:
     CLEAR green on black
     would clear  the screen and set the colors of the display
     to green letters on black background.
     
     
     Clear uses  ANSI escape  sequences. If the ANSI sequences
     are off,  clear sets  ANSI on  for the  duration  of  the
     process and restores the original situation at the end of
     the process. Unlikely to color-command, the colors change
     every time.  Still CLS-command  seems to  reset colors to
     their default values (white on black) if ANSI is off.
