Actually I was thinking much more in the lines of the VisualAge products. I 
don't
want DDS specs in the RPG. The concept of a bindable object is more in line with
my thinking. In fact, I would like the interface to be like the VA environment 
(use
BIFs to control color, underlines, messages, etc). That way the "screen" becomes
lower level (like MI vs RPG) and to generate a different protocol (5250 vs GUI 
for
example) is a function of the OS and not a compiler. Maybe if we had been doing
this for a few years, we would be ready for the OO world.
