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.
