Hi jivisampath,

Quote:

Means what...Do you have only two records in I/P file....

Quote:

Do you want to reverse the record by count.....

Please give some I/P & O/P example.....

Regards,

Priyesh.

Hi,
we can only open the tape files in reverese order.I think to reverese the sequential files we need to use sort steps in your job before actual processing.

If I am wrong please correct me.

INREC FIELDS=(1,80,SEQNUM,8,ZD) // assigns the SEQNUM to 81st col
SORT FIELDS=(81,8,ZD,D) // sort the seqnum in DESC order
OUTREC FIELDS=(1,80) // write the output excluding the SEQNUM.

To retain the original order use the same SORTIN JOB.

Please correct me If I am wrong.

hi narasimha_devi

zd means zoned decimal it is just like display formate in cobol.inrec and ourec are used for you want to operations on fields,if you wnt some field and dont want some fields all these operations performed using with inrec and outrec fields.

Before SORTING a record you can make some formatting in the INPUT records using INREC.
Where the OUTREC will do the formmatting after the records get sorted.
Thats the basic difference between INREC and OUTREC.

So for the SORT card I gave,

1. The SEQNUM will be inserted at the position of 81 in the INPUT records.
2. Then the records will get sorted for the SEQNUM (8 characters from 81st position)
3. OUTREC results in the formatting of output records , so the output will be the first 80 characters from the INPUT record thus eliminating the SEQNUM.

As thanooz told ZD represents ZONED DECIMAL which is nothing but a datatype as CH which represents CHARACTER.

Please correct me if I am wrong.
