I don't know about Modcomp, but that's not the IBM way.  IBM had
amazingly primitive file systems (at least through OS/360), but not
quite *that* primitive.  You could create files at anytime, but only
through JCL.  (Actually, I think it was possible to create files under
program control, but not via the standard APIs.)

The other bit of primitiveness is that OS/360 knew about the notion of
files on tapes that have names, but *searching* for a tape file given
its name (rather than position) was too hard a concept.
