Answer / 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

Answer / mailid

1.Read the file sequentially
2.For every successful read, move the key field to temp variable
3.when EOF is reached, A separate section should be performed in which Key field should not be moved to temp variable, Now, the temp variable will have key of the previously read record.
Using this, we can do a keyed read on the file to fetch the last but one record.
