Hello, I installed Emacs 23.1.1 and Octave 3.2.3 on my computer running Vista. To make Emacs find Octave, and to make Octave's prompt what Emacs expects, I added the following to the end of my .emacs file: (setq inferior-octave-program "C:/Octave/3.2.3_gcc-4.4.0/bin/octave-3.2.3.exe") (setq inferior-octave-startup-args (list "--eval" "PS1('octave:\# ');" "--persist")) When I do M-x run-octave, I get the "wait" cursor. I can see (using procexp) that Octave starts up as a child process to Emacs, but Emacs and Octave do not talk. Any insight would be much appreciated.
