This is drifting a bit off topic, but the IBM PC/AT-G, and PC/AT-GX (I
think that's correct, the "G" was for Graphics) were very popular in the
oil & gas business in the late 80s, early 90s...they were dual headed
bocks that ran GDDM-PCLK (PC link) and GDDM had support for developing
interesting graphical applications. One screen could show a 3270 full
screen type session, and the other screen a map or geologic cross
section.....very nice package. A lot of the actual vector rendering
processing was off loaded the the PCs themselves, so GDDM did have to do
as much work up on the host. You could even interact with the graphics
locally (pan, zoom, print, save, etc.) They even supported a small
digitizer type board.
I still have around here some place some geologic modeling programs I
developed for those boxes.

I seem to recall that IBM had a GML (DCF) type editor for PC-DOS as well.

I think it's safe to say that GDDM, as good as it was in it's day, is a
thing of the past now. But I still use it occasionally here, and the the
IBM PCOMM3270 emulator supports it and it's two separate graphics
formats just fine.
When I was young, I did have a short but interesting relation with the
GDDM-PCLK product. I think it used the same structured field file
transfer as IND$FILE to get the graphics data to the workstation
application for display and printing. It's probably now somewhere with
the GML editor and the PROFS front-end... ;-)
