Subject: JESS: Eval Salience
Hello,
I am trying to evaluate rules in a certain order declaring a salience
value like so (declare (salience 10000)), I have two rules defined one with
a salience value of -5000 and one with a value of 10000. I would assume the
one with the salience of 10000 would fire first followed by the one declared
-5000. The reason I want firing precedence is to be able to use a global
variable defined by the rule that should be firing first in the rule that is
firing second.
I am using Jess5.1, if anyone knows of anything that would help me figure
out how to handle this situation I would appreciate it.
Sincerely,
Ryan
