One is a field constraint disjointed connected the other is a Conditional Element 'or'. Details of both are covered in the manual. Suffice to say the first is like writting if ( stmt1.attrib1 == "X" || smt1.attrib1 == "Y" ) whil the ohte results in two separate rules, one checking "X" and the other checking "Y", both rules can match and fire.

Hi,

What is the difference between the following 2 statements

stmt1 : FactA( attrib1 == "X" || attrib1 =="Y")

stmt2: FactA( attrib1 =="X") or FactA(attrib1 =="Y")

Thanks

Jai
