1. how to view comp values in cobol
2. I have two sequential files (transaction & master), both have a common field called emp-no.
my requirement - Read transaction file and search whether trans-emp-no is available in master file. if available then update master file with transaction data else write a new record in the master file.
Thanks

Move them to corresponding Normal Variables and DISPLAY accordingly.

kalaignar_S,
This is a very simple two file compare.
Step 1. Both master and transaction file must be sorted in Emp-No order.
Step 2. Two file compare. (pseudo code)
| Code: |
OPEN INPUT MASTER-FILE
TRANSACTION-FILE
OUTPUT MEW-MASTER-FILE
READ MASTER-FILE AT END MOVE HIGH-VALUES TO MASTER-EMP-NO
READ TRANSACTION-FILE AT END MOVE HIGHT-VALUES TO TRANS-EMP-NO.
PERFORM
UNTIL MASTER-FILE-EOF
AND TRANSACTION-FILE-EOF
IF MASTER-EMP-NO = TRANS-EMP-NO
UPDATE MASTER-RECORD FROM TRANSACTION-RERCORD
WRITE NEW-MASTER-RECORD FROM MASTER-RECORD
READ MASTER-FILE AT END MOVE HIGH-VALUES TO MASTER-EMP-NO
READ TRANSACTION-FILE AT END MOVE HIGHT-VALUES TO TRANS-EMP-NO
ELSE
IF MASTER-EMP-NO > TRANS-EMP-NO
WRITE NEW-MASTER-RECORD FROM TRANSACTION-RECORD
READ TRANSACTION-FILE AT END MOVE HIGHT-VALUES TO TRANS-EMP-NO
ELSE
WRITE NEW-MASTER-RECORD FROM MASTER-RECORD
READ MASTER-FILE AT END MOVE HIGH-VALUES TO MASTER-EMP-NO
END-IF
END-IF
END-PERFORM
CLOSE MASTER-FILE
TRANSACTION-FILE
NEW-TRANSACTION-FILE
