OPEN INPUT FILE-1. IF CHECK-KEY1 > 0 DISPLAY "OPEN ERROR FOR FILE-1, CODE IS:" CHECK-KEY1 END-IF. OPEN EXTEND NEWFILE-1 IF CHECK-KEY3 > 0 DISPLAY "OPEN ERROR FOR NEWFILE-1 COD IS" CHECK-KEY3 END-IF. PERFORM READ-PARA THRU EXIT-PARA UNTIL EOF-REC = 'YES'. DISPLAY " FINALLY OUT OF LOOP" CLOSE FILE-1 CLOSE NEWFILE-1 STOP RUN. READ-PARA. ADD 1 TO I READ FILE-1 AT END MOVE 'YES' TO EOF-REC IF I > 3 AND < 10 PERFORM WRITE-PARA ELSE DISPLAY "NOT IN RANGE" END-IF. EXIT-PARA. EXIT. WRITE-PARA. WRITE NEW-REC FROM FILE1-REC.
