There are several ways, all of which depend on other parts of your program providing a signal that, in fact, all of the facts have been added. One is to make the rule in question depend on a pattern like "(all-facts-asserted)", and then when all the facts are asserted, you assert an "(all-facts-asserted)" fact, and then the rule will fire. The other way would be to put the rule into its own module MY-OTHER-MODULE and do *not* make it an auto-focus rule. Then when you have asserted all the facts, you can "(focus MY-OTHER-MODULE)" and then the rule will fire, and focus will return to the original module. --------------------------------------------------------- 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!)
