and backward chaining myself right now.</font>
<br>
<br><font size=2 face="sans-serif">Anyway, "ANSI Common Lisp"
by Paul Graham has a chapter on inference and it includes code for backward
chaining. You can download the code from here:</font>

<br><font size=2 face="sans-serif">That's where the inferencing code starts.</font>

<br><font size=2 face="sans-serif">"Paradigms of Artificial Intelligence
Programming" by Peter Norvig, as mentioned, is also excellent.</font>
