OS/400 isn't an OS, it's a way of life. :-)
The classic 'objects' that the operating system uses aren't really in a
filesystem. It looks vaguely like a file system (a very flat one), but
it isn't. An object can be examined by paging in the header area and
examining the type bytes embedded at a particular offset.
I don't want to clutter the list .. to read further search for 'single
level store' and AS/400 and that will give you the idea.
