*  BANNER is a program which prints large (5x7) block letters
* on the LST: Device in response to user input from the
* keyboard.  BANNER is invoked in several ways:
*	BANNER &lt;text&gt;
*		-- &lt;TEXT&gt; is printed on the LST: device; ex:
*			BANNER HELLO
*	BANNER /T
*		-- Multi-Text Line Input Mode; the user may
*		   type several successive lines to be printed;
*		   the user exits by typing ^C
*	BANNER /?
*		-- Built-In HELP Information is printed
*
