Hello,
I have a situation where I want to match a rule only
one time, but the rule has an or clause in it.
Here is a simple (not 100% syntactically correct)
example.
(defrule ruleA
(or (value1 ?v1) (value2 ?v2))
==>
(printout t "GOT IT" crlf))
if I were to assert two facts,
(assert (value1 Yes))
(assert (value2 No))
And do a (run), I will get two matches. I looked at
unique, but that can only be used
with one value.
I also tried exists, but I have had no success.
I would like for "GOT IT" to be printed out
only once.
Thanks,
Bob Stewart
