Hi,

How do we can copy an existing ESDS records to another ESDS/Flat file in reverse order? (Assumption - # of records unknown, should not use any Language)

Example - Assuming we have 5 records in ESDS-

1st Record
2nd Record
3rd Record
4th Record
5th Record

New ESDS/Flat file should look like

5th Record
4th Record
3rd Record
2nd Record
1st Record

Regards,
Murali Mohan K

Hi,
I believe sort can be used for this.

Here's a DFSORT job to do what you asked. I assumed your ESDS has fixed 80-byte records. But you can change the job appropriately for other attributes.

Code:

//S1 EXEC PGM=ICEMAN
//SYSOUT DD SYSOUT=*
//SORTIN DD DSN=...   original ESDS
//SORTOUT DD DSN=...  new ESDS
//SYSIN DD *
  RECORD TYPE=F
* Add sequence number.
  INREC OVERLAY=(81:SEQNUM,8,ZD)
* Sort in descending order on sequence number.
  SORT FIELDS=(81,8,ZD,D)
* Remove sequence number.
  OUTREC BUILD=(1,80)
