I picked up a book in the early nineties called File Structures or File Systems: I've
forgotten which,
because I didn't read it as much as I had intended. It covered the IBM MVS mainframe
dataset file and
directory structure and the Unix file and directory structure. And yes, I was referring to
the MVS dataset,
as much of it as I can remember from that book. (I sorry I can't recall the exact
title: the book is
somewhere at the bottom of a pile of other books from my last move several years ago.)

'fraid so. The Unix directory structure and
the correlating
free-form file competed with the file-as- record-structure and
directory-as-record-structure in the seventies and eighties. The
competition had finished by the nineties, and hardly anybody
remembers it now.
Sorry, I don't understand this. Can you give an example of
file-as-record and directory-as-record? Some of it suggests MVS, but
not quite.
