Arnold: ==== Or, if you have moved beyond the era of simulated glass teletypes on graphics screens, you could do the editing in the terminal (program). It's a real shame the mux/9term way of doing things never caught on. I suppose it is because so many people are wedded to programs that require cursor addressing; I'm glad I never succumbed to that. I use ed (or its cousin qed a la Toronto) for simple stuff. Mostly I'll use the traditional commands, but sometimes I will, in mux/9term style, print a line with p, type c, edit the line on the screen, pick it up and send it, type . return. And of course I can do that sort of thing with any program, whether or not it is compiled with some magic library. All this is something of a matter of taste, but I have sometimes amazed (in a good way) my colleagues with it. Norman Wilson Toronto ON
