Hmmm, not really awake yet I guess. THIS one is correct: (sorry for the mail-bombing)
(do-backward-chaining A) (do-backward-chaining B) (do-backward-chaining C) (defrule succeed-A (A ?) => (printout t A)) (defrule get-A (need-A ?)

(assert (B (read)))) (reset) (run) -------------------------------------------------------------------- To unsubscribe, send the words 'unsubscribe jess-users [EMAIL PROTECTED]' in the BODY of a message to [EMAIL PROTECTED], NOT to the list (use your own address!)
