Are you shure ? 
I tried: 
  01 a pic x value "S".   
  01 b pic x value "S".   
 ** ----------------------
  PROCEDURE DIVISION.     
      if (a equal "S"     
      and b equal "S" )   
          display "( OK"  
      end-if              

      if  a equal "S"     
      and b equal "S"     
          display "  OK"  
      end-if              
      GOBACK.             

And it behaves normally (both ILE and CBL, V5R1M0) 

Sincerely
Domenico Finucci

Oggetto: [COBOL400-L] Question about evaluation of a conditional
statement.


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
