       I am looking for a way of display-
  ing sixels then redisplaying part of the screen.  Without redrawing the
  whole screen.  This is to be done on a VT240 or VT330 ????
	Is there a way of accessing the screen memory and then replacing part
  of it ?  Any suggestions greatly appreiciated.  Hoping the screen mem
  can be grabbed?  Where does this lie??

	Thanks
