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.

HI FRIENDS,
AS U MENTIONED THAT, IT WAS A PS-FILE,SO IN UR COBOL
PROGRAM, U HAVE DECLARED AN KEY-VARIABLE IN INPUT-PS-FILE.
WELL, SO, YOUR WAY OF APPROACH WAS WRONG.
HERE IS THE RIGHT CONCEPT:
In a PS-FILE, you cannot use any key-variable. only record-
number if you have defined for a particular record can be
moved, so that,a particular record can be moved with its
record-number.
In order to move your choice of records to be moved to any
other file, try to make use of VSAM-Files, which enables
you to define your own set of records to be moved from one
dataset to other, by using either IDCAMS utility, SKIP AND
COUNT in your JCL, (OR) making your cobol code using the
key-variables set to your fixed number of choice of record-
index between the range of your choice of records.
well, these are the only possibilities to move records from
one file to other file.
