DEFINE A TABLE

01 TABLE.
05 TABLE-A OCCURS 500 TIMES
INDEXED BY IDX
10 TEXT PIC X(100)
10 COUNT PIC9(4).

01 W-REC PIC X(100).
01 W-OUT PIC X(100).
01 SUB S9(4) COMP VALUE 0
PROCEDURE DIVISION.

INITIALIZE TABLE-A

READ-PARA.
READ F1 IN W-REC
AT END
SET IDX TO 1
PERFORM VARING SUB FROM 1 BY 1 UNTIL SUB > 500
IF COUNT(IDX) > 3
WRITE W-OUT FROM TEXT(IDX)
ELSE
SET IDX UP BY 1
END-IF
END-PERFORM
STOPRUN
NOT AT-END
CONTINUE
END-READ

SEARCH TABLE-A
AT END
PERFORM TABLE-ENTRY
WHEN W-REC = TEXT(IDX)
ADD +1 TO COUNT
END-SEARCH

GO TO READ-PARA

TABLE-ENTRY.
SET IDX TO 1
PERFORM VARYING SUB FROM 1 BY 1
UNTIL SUB > 500
IF TEXT (IDX) = SPACES
MOVE 1 TO COUNT (IDX)
MOVE W-REC TO TEXT (IDX)
ELSE
SET IDX UP BY 1
END-IF
END-PERFORM
