However, if there are a fixed no. of records, as you have
mentioned in the question - which may not always be the
case with Production Files(They may contain millions of
records), you may follow this approach.
1. Read all the records into a COBOL array(table) A
(1,2,...10).
PERFORM VARYING I FROM 1 BY 1 UNTIL I>10
READ INPUT-FILE
MOVE INPUT-RECORD TO WS-RECORD(I)
END-PERFORM.
2. Print the data from the COBOL Array into Output-file.
PERFORM VARYING I FROM 10 BY -1 UNTIL I<1
WRITE WS-RECORD(I)
END-PERFORM.

Answer / quasar chunawala
There is no such facility on Mainframe COBOL to read a
Sequential File(PS), backwards. PS(Physical Sequential)
files are meant to be read in a straight-sequential fashion
record-by-record one at a time, till you reach the Desired
record.
