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.)
