EDT and TPU are both hardcoded for VTxxx terminals. They put it in because everyone was whining for them to do it, but it is too slow to use for anything intensive as editting. It is used for other things, which is why I know it is so slow (the debugger leaps immediately to mind). The bottom line is DEC really doesn't want you using non-DEC terminals. I hear gnu emacs works very well on non-DEC terminals on VMS (it must therefore not use SMG either!). -- Terry Poot The McCall Pattern Company I personally think that Gnu emacs on VMS writes to the screen MUCH more efficiently than edt or eve even on vtxxx terminals. This is one of the major reasons that I prefer emacs over any VMS editor. For example I am reading the news from home using emacs (on unix but the essential argument follows through). When I read the above included message and I decided to follow up on it, instead of repainting the included message, emacs just left it on the screen but shifted it right three characters! Hence, I'd say a factor of at least ten was gained in achieving the desired effect. At 1200 baud this is significant. If you want to test this yourself and you have emacs on your system then do the following: 1. Edit a file using eve. 2. Now make two windows and note how eve does it. 3. Do the same in emacs and see how it should be done. (factor of two faster) -- John bitnet: davis@ohstpy internet: davis@pacific.mps.ohio-state.edu
