                 'Vt$clr' is used to clear the screen on the user's terminal.
                 The  return  value  is OK if the screen was cleared, and ERR
                 otherwise.

                 The VTH common block is checked for the existence of a clear
                 screen sequence.  If one exists, it is written out, 'vt$del'
                 is called to print out a small delay sequence, and the func-
                 tion return is OK.  If no sequence  exists,  the  return  is
                 ERR.
