A rule like (defrule top-employee ?e <- (employee (name ?name) (salary ?s)) (not (employee (salary ?s2&:(? ?s2 ?s)))) ... Matches the highest paid employee. You can process this one fact, then remove it, or modify it so it no longer matches, or assert a flag of some kind; and then the rule fires again for the next highest. Alternatively, you use a defquery to get all the employees, then sort the list in Java code. --------------------------------------------------------- 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!)
