Answer / abhishek

First open file-1 as:

OPEN INPUT FILE-1 REVERSED

->If REVERSED clause is specified at the time of opening a
particular file, then that file can be read in reverse
direction.

Now we can read file-1 like
READ FILE-1
INTO ws-record
NOT AT END
PERFORM PARA-1
END-READ

PARA-1
WRITE FILE-RECORD
FROM WS-RECORD
END-WRITE
