<P>You can use Emacs to edit LISP code: most Emacses are set up to enter
LISP mode automatically when they find a file which ends in .lisp, but
if yours isn't, you can type <CODE>M-x lisp-mode</CODE>. M-x means: meta-key
plus x. If there is a meta (or ALT) key try it. If this fails M-x can
be typed by typing ESC followed by x. If your keyboard lacks an ESC
key, curse DEC, and type control-[ followed by x.</P>
<P>You can run LISP under Emacs, too: make sure that there is a command in
your path called "lisp" which runs your favorite LISP. For example, you
could type</P>
<P>
<BLOCKQUOTE><CODE>
<PRE>
ln -s /usr/local/bin/clisp ~/bin/lisp
</PRE>
</CODE></BLOCKQUOTE>
</P>
<P>This isn't needed in CMUCL. Lisp is called lisp there.</P>
<P>Then in Emacs type <CODE>M-x run-lisp</CODE>. You can send LISP code to the LISP you
just started, and do all sorts of other cool things; for more
information, type <CODE>C-h m</CODE> from any buffer which is in LISP
mode. This means: press control <EM>and</EM> h, release both and press m.</P>
<P>Actually, you don't even need to make a link. Emacs has a variable
called inferior-lisp-program; so if you add the line</P>
<P>
<BLOCKQUOTE><CODE>
<PRE>
(setq inferior-lisp-program "/usr/local/bin/clisp")
</PRE>
</CODE></BLOCKQUOTE>
</P>
<P>to your .emacs file, Emacs will know where to find CLISP when
you type <CODE>M-x run-lisp</CODE>.</P>
