              ------- LINE (Function Key) -------


--  To draw a straight line with this function key, there must be 
    two flashing "+" on the screen.  One is called the cursor and
    it can be moved around the screen using the cursor control keys.
    The other flashing "+" is called the "from pt".

--  If there is only one flashing "+", simply press one of the 
    cursor control keys and the one "+" will become two.

--  Press the LINE function key and a straight line will be drawn
    between the from pt and the cursor.

    NOTE  After drawing a line, the from pt and the cursor are at the
          same point; therefore, you will only see one flashing "+".
