Some rules get transformed in various ways as they are compiled -- for example, "|" connectives are actually transformed into "or" function calls, and ppdefrule will show them that way. And Jess inserts an "initial-fact" pattern in various situations; this is described in the manual. But I think this is only case where Jess inserts a pattern than matches a user template. As I recall, it was done for defensive reasons: because if Jess doesn't insert that pattern, then if people don't include it themselves (which is the right thing to do 99.99% of the time) there will be extra, spurious firings of the need-X rules, and I got tired of explaining why they were happening. --------------------------------------------------------- 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!)
