Not at all, more a reflection that this topic has a bewildering multitude of incompatible and aften complex APIs in the world outside Forth, so what should our (one) graphics API target? By contrast, text I/O has pretty much one API on the C level, even though what's behind that can be quite diverse (display on a serial terminal, the console, a local terminal emulator window (with lots of terminal emulators available), through ssh on a remote terminal emulator, on a local terminal emulator with a display on a remote X server, an emacs terminal buffer, etc.), so it's relatively easy to support. > Anton, in your answer to Joe, I can hardly figure what "open a pipe" means > in reality for me, https://www.complang.tuwien.ac.at/forth/gforth/Docs-html/Pipes.html And I just rediscovered an example of how to use that for graphics: http://www.complang.tuwien.ac.at/forth/programs/ps-example.fs > or "through the C interface" etc. For Gfoth 0.7: https://www.complang.tuwien.ac.at/forth/gforth/Docs-html/C-Interface.html It's slightly different in the current development version: https://gforth.org/manual/C-Interface.html Then you look at the C graphics API you want to use, and call the C functions through the C interface. > Reading this I imagined that if only there is a single (Forth) word, for a > given OS ok, to draw a pixel where I need it with graphic attributes, That > would be cataclysmic in the Forth world.

When I posted about ps-example.fs in 2010, there was not much reaction; maybe once you are in heaven, there is no desire to post.:-)
