Subject: JESS: First try with backward-chaining
Hi,
I tried for the first time to use backward-chaining and I can't figure
out
why this simple example don't work :
(deftemplate x
(declare (backchain-reactive TRUE))
(slot a)
(slot b)
)
(defrule printX
(x (b 12))
=>
(printout t "yeah!")
)
(defrule createX
(need-x (b ?y))
=>
(assert (x (a 3) (b ?y)))
)
(run)
Thanks !
