I have a PS file to be read in reverse order and process accordingly. Do we have a way to mention to read the file in reverse order in FD in COBOL module? OR do we have something to achieve the same using SORT?

Note: Reading the records into a buffer (array) and using it in reverse order would be the first idea that comes to mind but that way doesnt work for file with millions of records.

Your suggestions will be appreciated.
