The basic rules regarding any file states that a file first line must be a header and last row must be a footer for a particular file.
So while reading your data you can provide validation and can handle all the situations differently as per your business needs.

Answer / guest
If a source file will have header and footer, then header record will start with 0, trailer record will start with 9 and the detailed record will start with 1.
so the first record starts with zero, next 8 records with 1 and the last record with a 9.
