Well, I don't remember that far back personally, either. But Eric
Raymond claims it was Tim Paterson who wrote Quick and Dirty OS in six
weeks at http://catb.org/~esr/jargon/html/M/MS-DOS.html, which bears
out what I've heard elsewhere.
Dos 1 never had subdirectories: that came in DOS 2. DOS 2 was intended,
back in those dim distant days, to be a migration path to Xenix, a
rather awful port of Unix to run on the PCs of those days. So that's
where the Unix-a-like syntax came from. (The PC market didn't want to
migrate, unless they could run all their existing programs as well as
they could on DOS. This started a trend that has been the Curse of the
Computer Industry for the next twenty-odd years).
I don't think IBM got seriously into DOS code until around DOS 4, when
it was obvious that it was going to be a major IBM product line.
