Absolutely -- use defmodules (new in Jess 6,) that's what they're for.

A wise man said, "Premature optimization is the root of all evil." You're worrying about a phantom problem, here. By sharing the joins, you're reducing the total potential workload. Assuming at least one of your on/off rules is generally on, and assuming that some on/off rules share joins with other rules, then the most efficient thing is to have those joins always "active," since otherwise there's a large amount of work done every time the rules are turned on or off. > > BTW: 1) the Jess website: http://herzberg.ca.sandia.gov/jess/ > appears without any letters in Netscape 4.76 recently (black > letters on black background, it seems). In IE it's okay. You're the second person who has mentioned this, so I'll have a look. I have Netscape 4.76 for Linux right here, and the page looks fine. Anybody who knows me knows that I'm proud to be able to claim I've never used IE, ever! A moment's experimentation shows that the white letters turn black whenever the page is sufficiently narrow that the red text in the heading has to wrap across two lines -- make the browser window wider, and it reappears. I'll see if I can fix it somehow. --------------------------------------------------------- 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!)
