[TUHS] Re: screen editors, Where/when did TUIs come from

It appears that Greg A. Woods <tuhs(a)tuhs.org> said: At Yale we had one called "e" that ran on our early bitmap terminals. Although programs could directly write arbitrary graphics to them, the editor used them as text terminals via the system terminal emulator I wrote. I made a few tweaks to help the editor like insert mode to push characters out of the way rather than having to redraw the line each time, and an input mode that buffered up characters until you typed something that needed more than an echo to the screen. It was based on Ned Irons' PDP-10 screen editor that ran on Omron glass ttys, and was a cousin of INed which Walt Bilofsky wrote for Interactive Systems. They used the quarter-plane model, you could move the cursor around the screen and overtype stuff, with no automatic flow from one line to another. There were control characters to do the other editing stuff like search and save/exit, but nowhere near as complicated as emacs. R's, John
