Yes. If this isn't what you ant, then if the right-hand-side takes some measurable action, then you can add a negated pattern to the left-hand-side to detect whether this has occurred yet; i.e., (defrule foo (or (a) (b)) (not (c)) => (assert (c))) --------------------------------------------------------- Ernest Friedman-Hill Distributed Systems Research Phone: (925) 294-2154 Sandia National Labs FAX: (925) 294-2234 PO Box 969, MS 9012 [EMAIL PROTECTED] Livermore, CA 94550 http://herzberg.ca.sandia.gov -------------------------------------------------------------------- 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!)
