Hi..

I have 2 sequential files (master and transaction) having a common field (called empno).
How can i check whether the empno available in master file not in transaction file and vise-versa?

Please help in this regard.

Hi,
You need to write a sepearate sort step(s) in which, both the files are sorted on empno key.

Then you can write a cobol program based on key matching algorithm. With this approach, you need not open and close both the files more than once.

Thanks,
Parikshit.

Hi,

Pls refer the below code for ur prob.

Code:


C300-CHECK-KEY-MATCH SECTION.
********************************************************
 THIS PARAGRAPH PERFORMS KEY COMPRASION OF MSTR
 AND TRANS FILE
********************************************************

    IF X06-TRANS-KEY  = X05-MSTR-KEY
         PERFORM C310-CHECK-DATA-MATCH
         PERFORM C100-READ-TRANS
         PERFORM C200-READ-MSTR
    ELSE
         IF X06-TRANS-KEY  < X05-MSTR-KEY
            MOVE 'B' TO X04-RECORD-MATCH
            PERFORM C400-ERROR-MSG
            PERFORM C100-READ-TRANS
         ELSE
            MOVE 'M' TO X04-RECORD-MATCH
            PERFORM C400-ERROR-MSG
            PERFORM C200-READ-MSTR
         END-IF
    END-IF
    .


Thanks,
Dipanshu G.
