You just write a single rule that matches one fact that needs changing, plus any other facts that supply needed data, and do the modification on the RHS. The rule would fire once for each eligible fact. This may cause an infinite loop -- that can happen when you match a fact on the LHS and modify it on the RHS. If you're using Jess 7 (and you should be!) then use the "no-loop" declaration on this rule to avoid the problem. --------------------------------------------------------- Ernest Friedman-Hill Advanced Software 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!)
