Write a JessEventListener to handle FACT events. Remember that (modify) is implemented as a (retract) followed by an (assert). Manual section 4.10 covers JessEvents, and includes a sample handler that counts facts being asserted and removed. In general, I recommend that people embarking on a Jess-based project read the whole manual all the way through at least once, to get some familiarity with all the concepts. --------------------------------------------------------- Ernest Friedman-Hill Distributed Systems Research Phone: (925) 294-2154 Sandia National Labs FAX: (925) 294-2234 Org. 8920, MS 9012 [EMAIL PROTECTED] PO Box 969 http://herzberg.ca.sandia.gov Livermore, CA 94550 --------------------------------------------------------------------- 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!)
