The Message routine is used to put a literal anywhere on the screen for such things as screen border titles. Its advantage over PRINT is that it saves the screen it overwrites automatically and it can be "unprinted". Its use is similar to that of VIDEO.RW. Calling syntax is

       CALL MESSAGE (X,Y,MSG,ATTR,ACTION,IMAGE)

where

       X        is the X position of the literal
       Y        is the Y position of the literal
       MSG      is the literal to display
       ATTR     is the display attributes
       ACTION   is the action to take.  "UP" places the literal on the
                screen.  "DOWN" removes it
       IMAGE    is the saved screen image
