I would like to see x3270 support GDDM graphics. It would come in handy viewing the GDDM graphics displays the IBM Performance Toolkit for z/VM produces now without having the extra hassle of making a csv file, downloading it to Excel and making a graph there.

Our SAS/MXG performance guy back in the day had a Memorex 3279G look-alike with its own printer that printed the screen image when the hardcopy print key on the terminal's keyboard was pressed. IBM may have had similar hardware, but OEM stuff was cheaper. We did have a real 3279G which exhibited the "green lightning" while the LPS (load programmed symbols) data stream was being processed.

Graphic output on the mainframe (was: Shocking Bug in Latest PCOMM Release)
We used GDDM and 3279 G (IIRC) displays to do preview of our plotter outputs (which were to pe printed on big electrostatic Calcomp plotters in the end). The (most technical) software was written in Pascal and Fortran and built the output using a graphic software which was called GKS (graphic kernel system). GKS had two adapters, one for the Calcomp plotter and one for GDDM, so the output (GKS metafile) could be plotted and shown at the display station at the same time. Later we added an adapter to HPGL (HP graphics language) and bought some HP plotters. This was in the 1985 to 1995 time frame. After that, the applications moved off the mainframe, to Unix workstations. IIRC, some other companies here in Germany (car manufacturers) did similar things, in the same time frame. There were even some CAD like systems running on the mainframe. Kind regards Bernd Am 26.11.2017 um 21:01 schrieb Seymour J Metz: What is "GDDM graphics", APA or PSS? -- Shmuel (Seymour J.)
