I have 20 steps in a job... step01, 02....step17...step20. For some reason I want to execute step17 only if the return code for all the previous steps are less than or equal to 4. otherwise if return code for any of the previous 16 steps is greater than 4, then step17 should be bypassed. How do I do that ?? how and in which step should i formulate COND parameter

I have PS flat file with 14 records. I want to read from 4th to 9th record and want to write those 6 records (4th record to 9th record) to another PS file (output file). there is no key defined in the input file. I just want read a certain Consecutive records. can any one please give me the procedure division Coding for this. I have coded the below coding but the READ-PARA is performing only 1 time even though I have 14 records in my input file (i.e FILE-1): PROCEDURE DIVISION. A000-SECTION. MOVE 0 TO I. 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.
