	Well, since everyone wants to add protection bits to the DOS, why
don't we go the whole nine yards?

	d:  Delete protect (file cannot be deleted)
	w:  Write protect
	r:  Read protect
	i:  Information protect (file will not appear in directory scans
	    unless a special flag is provided)
	n:  Name protect (file cannot be renamed)
	s:  Size protect (file size cannot be changed)
	p:  Protection bit protect (protection bits cannot be changed)
	b:  Backup protect (don't bother backing up this file)

	Wow!  Eight bits exactly!

	Believe it or not, except for the 'b', there was an OS that actually
had all these protection bits.  It was called PTDOS, for the SOL-20 and
Helios 8" drive.  After looking through the PTDOS manual, it struck me that
it would make an ideal BBS operating system:  Arcane, and files could be
hyper-protected if you wanted (making it a pain to hack).

	My favorite feature was the KILL command, for deleting files.  When
you ran the KILL command, it would not only remove the file from the
directory, but write garbage into all the sectors it occupied.  When you
KILLed a file, it was *GONE!*  Must have been a big winner with the DoD...
