Hi Felix, BTW -- I think that Brian was intending
;; Set the focus stack (focus A B) (run) There is nothing to preclude you from using modules and salience together. There is an essay on the proper use of salience on the Jess wiki here <http://www.jessrules.com/jesswiki/view?SalienceUsageTips>. Salience is best used to control the priority of sets of rules within a module. It should NEVER be used to control the priority of any individual rule. Of course, a set of rules may have just a single member at a particular time, but the principle holds in general as stated. The best way to think about salience is that it is to liken it to the old GOTO statement; terrible if you use it to create spaghetti code, but useful if you take care to create "structured gotos" (e.g. labled statements).
