I don't see why this would make your point.
mmap() (or equivalent) services should be available
on all systems with native support for an MMU,
which includes Unix, WNT and possibly also VMS.
It's usually the fastest way to do I/O
and saves a lot of real memory when large files
are to be processed. It has nothing to do with
record stuff in the first place, although
record oriented I/O could be implemented on top
of it.
But this is an issue for the app under consideration,
not the OS. On the OS level, records are an anachronism
and cause nothing but trouble. When switching from
VMS/MVS to Unix many moons ago, I did not miss them for a second.
