Answer Posted / lakshmi
1) iN WORKING STORAGE SECTION, Declare 2 variables HOLD-REC
and PRV-REC Equal to length of file and initialize them to
spaces
2) In Procedure divison, use the below logic and at the end
of the file read, PRV-REC contains the record before the
last record
READ <INFILE>
NOT AT END
MOVE HOLD-REC TO PRV-REC
MOVE INREC TO HOLD-REC
AT END
MOVE 'Y' TO EOF
END-READ
