1. Start the DB file with field1 and field2.
2. Read the DB file next record and increase the counter
value.
3. End the process, when end of file reached.

Answer / srinivas
Declare below three variables in working storage section.
77 WS-COUNT PIC 99. VALUE ZEROS.
77 WS-VAR PIC X(10) VALUE "WELCOME".
77 WS-USERID PIC x(5) VALUE "AAAAA".
Decalre one indicator for end of file.
04 EOF-DB-FILE PIC X VALUE "N".
88 EOF-DB-FILE VALUE "Y".
Read each record from input file(Db file) and increase
count if the conditions are satisfied.
PROCEDURE DIVISION.
OPEN INPUT DB-FILE.
READ Db-file
AT END MOVE "Y" TO EOF-DB-FILE
GO TO 1000-EXIT.
IF FIELD1 = WS-VAR AND FIELD2 = WS-USERID
ADD 1 TO WS-COUNT
END-IF
GO TO 1000-EXIT.
DISPLAY WS-COUNT
CLOSE DB-FILE.
STOP RUN.
