*Keyed lookup via a custom built B-Tree system typical of what is used in most modern databases.
*Fast retrieval.
*Always sorted.
*Scroll backwards or forwards from any position and remain in order.
*Multiple keyed systems per file allowed.
*Records automatically resued after deletion so no packing of space is necessary.
*All commands are simple to use straight from your program.
*Both KFS and DFS can work independently from each other.
