While reengineering a program, I created the following conditional
statement:

IF (WS-RISK-CODE = "FX" AND  
   WS-ORDER-DOES-NOT-EXIST)
        <perform some statements>
END-IF.

The conditional statement was evaluated false during the program run even
though WS-RISK-CODE equalled "FX" and WS-ORDER-DOES-NOT-EXIST was true. None
of the statements to be performed were performed.

I then removed the parentheses to result in the following:

IF WS-RISK-CODE = "FX" AND  
   WS-ORDER-DOES-NOT-EXIST
        <perform some statements>
END-IF.

This worked.

I'm not sure I understand how the parentheses caused the problem. I assumed
the order of evaluation within the parentheses would be the relational
operator first and then the logical operator. 

Can someone explain it to me?

Thanks,
Kelly
