There is a file say in the order 1 to 10 and I want it reversed in the order of 10 to 1.
I think it is possible thru FILE-AID (batch) but in the meanwhile if anyone can suggest another way to do this in a JCL. We have SYNCSORT resident at our site in case someone has a solution using SORT.

Abhi,
The following JCL will give you the desired results.I am assuming that your input file is lrecl is 80. we add a seqnum for each record and sort on that seqnum descending.By doing so the order will be reversed. While writting the output we remove the seqnum.
