   GDDM didn't provide GUI functionality per se, more 
application-oriented graphics.  Due to the way the 3270 datastream 
works, implementing a GUI as we think of them isn't terribly practical.

   That's not me trash-talking 3270; it's very well-designed and it 
works amazingly well for what it was designed to do.

   We regularly run GDDM applications on 3290 and other graphics 
terminals at LSSM.
