Do you really know anything about Display PostScript? Have you ever looked up the word "superset"? Please be careful what you say out there, folks. There are lots of opinions, and we want to share useful information, not post flames. The Display PostScript's operator set and NeWS are intersecting sets, where Red Book PostScript is roughly the area of intersection. They are completely different implementations, and differ in many other ways, but it is incorrect as well as a trivialization to say that NeWS is a superset of Display PostScript. And also, Display PostScript has nothing to do with X windows, other than the ability to ge integrated into it. The NeXT machine does not run X windows; it draws its windows with Display PostScript. Sigh. Glenn Reid Adobe Systems

I think that what was meant by News being a 'superset' of Display Postscript was that News includes higher level Window manager type abilities. This assumes that other than that they cover the same functionality. (Which I suspect is very debatable.) I hate it when these discussions get unpleasantly personal.

I just received the "Display Postscript preliminary documentation" (thanks Glenn), which I have so far only had a chance to glance at. What I did notice, however, is that input does not seem to be well supported. I understand, from following various comments in this forum that the reason is that DPS is really only meant for output, and supposed to run -with- a windowing system. So now I'm confused. Users of NeXT and Glenn, would you say DPS is a suitable basis for creating window systems with the associated paraphernalia ? would you claim that it is one component from several, making up a WISIWYG sort of interface? More pointedly, how does DPS support interaction between the cursor and "interface objects" ? Andy Andrew Dwelly E.C.R.C.
