Section 4.7 of the manual explains this class, and has a few good examples. The 6.1a4 manual includes the most information. But using Fact is more complicted than just asserting the facts from Jess. Unless you've got a severe performance constraint, it'd be much easier to simply use Rete.executeCommand() to call (assert), and the returned Value will be a FactIDValue, which is what you want. > Is there any book availabe on JESS, if so could someone tell me from where I >could purchase it and what the price of the book is. Funny you should ask... my book on Jess is currently in production, and should ship in April 2003. It's from Manning press, and Amazon will have it, as will A Bookstore Near You (Border's will be a good bet.) --------------------------------------------------------- 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!)
