Answer Posted / 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.
