Oh yes, It's really what my want. Thanks a lot.

thanks.

I am reading Practical Common Lisp and now I understand the correct code should be:

(lambda (f) (apply f '(1 2))) '+ )

I'm using GNU Common Lisp(gcl), when I wrote:

( (lambda (f) (f 1 2)) '+ )

gcl complains:The Function F is undefined. why? It's invalid to pass a function to lambda macro ?
