01 INP-VAL PIC 9(3).
01 WRK-VAL PIC 9(3).
01 I PIC 9(3).
01 QUT PIC 9(2).
01 QUT1 PIC 9(2).
01 REM PIC 9(2).
01 FLAG PIC X(1).

PROCEDURE DIVISION.

STEP-1.
MOVE 40 TO INP-VAL.
DISPLAY "Please find the prime numbers below:".
IF INP-VAL > 2 THEN DISPLAY "02".
PERFORM STEP-2 VARYING WRK-VAL FROM 3 BY 1 UNTIL WRK-VAL > INP-VAL.
STOP RUN.

STEP-2.
MOVE "Y" TO FLAG.
INITIALIZE REM, QUT, QUT1.
DIVIDE WRK-VAL BY 2 GIVING QUT.
PERFORM STEP-3 VARYING I FROM 2 BY 1 UNTIL I > QUT.
IF FLAG = 'Y' THEN DISPLAY WRK-VAL.

STEP-3.
INITIALIZE REM, QUT1.
DIVIDE WRK-VAL BY I GIVING QUT1 REMAINDER REM.
IF REM = 0 THEN MOVE "N" TO FLAG.
