hi  all   
I've just finished reading chapter 2 of  Paradigms of ai programming
by norvig but i can't get his generate program to work.

i'm using cormans lisp on a mac and i've checked and rechecked
everything but still no luck.

when i type (generate 'sentence) i get (sentence) instead of for
example (the girl hit the ball). if i type (generate 'verb-phrase)
i get (verb-phrase).  obviusly something is drastically wrong, but i
can't see what.

please guys i need help with this because otherwise i can't proceed
with the book.
thanks.

There were already several responses to your previous posting of the 
same problem.  Please check that original thread.
