Keyed

Keyed access to files allows access according to a specified key (or part of the file).

This method causes the file pointer to locate the record you want starting with the one containing a specified value in the data field. If the system finds that there is no record with such a value, it goes on to access the first record containing a data value higher than that which was entered.
