[rules-users] Convert logic to DRL rules

Hello, I am a new Drools user trying to convert the following simple logic into DRL: IF (Person.Age > 35 OR Person.Age < 25) AND (Person.ZipCode = 23546 or Person.ZipCode = 68590) THEN Person.Status = "KT"; I found that it is not easy to convert the above logic into ONE DRL rule. I tried something like this when $a: Person(age>35) or Person (age<25) $b: Person(Zipcode==23456) or Person (ZipCode == 68590) $c: $a and $b Then $c.setStatus("KT") But looks like I can not use $c: $a and $b becaue in Drools, you can only bind variable to column, not to other varaibles. Please advise how to do this. I would imagine this should be quite simple, maybe I missed something quite obvious. I know that I can write custom Java method to do this, but if I do that, I suppose I lose the power of RETEOO pattern matching (pattern resuing, etc.). So I prefer not to do that. I also understand I can break the above logic into 4 rules and that would be quite easy, but our business user is not used to think in that way. Also, we have more complex logic than the above. So what I want is to see if there is a way to convert this kind of logic in ONE DRL rule. Thanks in advance. Bill
