I also have some nagging memory that RMS caches filesize on open, and
it's rather tough to get it to re-evaluate how big the file is
without closing and reopening the file.
FWIW, playing around with some of the VMS hidden commands (which I've
forgotten about--it's been too long) to see what system calls are
being made when you type/cont would give you an idea of how type's
doing it.
