Octave mode in Emacs

[Matthew Reich]

A few questions about Octave mode in emacs

1.  Does XEmacs support Octave mode?

2. Attempting to enable Octave mode, I added the code listed in section H.1of 
the GNU Octave manual to ~/.emacs.  That causes the following error message on 
Emacs startup:
    Warning (initialization): An error occurred while loading 
`/home/REICHM/.emacs'\:
    Symbol's value as variable is void: ’octave-mode

The following files are present:
   /usr/share/emacs/24.3/lisp/progmodes/octave-inf.elc
   /usr/share/emacs/24.3/lisp/progmodes/octave-mod.elc

How should the file locations and ~/.emacs be changed?

3. Where can I get octave-hlp.el (.elc)?

4. Emacs has (at least) one odd behavior; the Backspace key acts like C-h.  Any 
suggestions?

Thank you,
