Right. And since this is an OS capability (which Unix lacks), not a
language capability, I think it is better to talk about Unix-style
streams, not C-style streams.

Any language includes C. I haven't programmed in C on VMS, but my
understanding is that the C library works works fine with fixed length
records on VMS. Indeed I think that VMS was a major reason for some
restrictions in the C standard.
