You've run into a bug in the rule compiler for the new pattern syntax. This was previously reported and has been fixed for the next release (7.0RC1, due very soon!) For now you can use the equivalent old syntax: (MAIN::patient (age ?age) (weight ?weight&:(or (>= ?age 14) (>= ?weight 50)))) --------------------------------------------------------- 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!)
