Finally, I will note that, if you develop an incurable allergy to emacs, there are other editors that offer reasonable support to programmers. The textbook devotes an entire chapter to vi, which does not offer much support for programming, but a reasonable option is vim ( “vi improved” ).

Like emacs, vim is available on many, but not all, Unix systems and, once you have learned it, you can use it over telnet via keyboard commands. To learn the basics of running vim, give the command vimtutor.
