Dues it save space?

Well yes and know.  It saves space in that the first reused record does not 
cause a file extension.  On the other, once the file is fill (zero deleted 
records) nit not only doesn't save you space, but it causes you a little 
additional because of some overhead that the re-use function causes.  I 
don't remember the algorithm, bit I vaguely remember that it's one byte of 
overhead for each eight records plus a fixed amount, but don't take this to 
the bank.
