Hmm.  I think you are confusing operating systems and file systems.
What if a "64-bit OS" had a "32-bit filesystem" or a what if a "32-bit
OS" had a "64-bit filesystem"?

In all ways, or just this one? :-)  I suppose it depends on whether
the open system call succeeds, and that really depends on the
underlying OS and filesystem more than Octave internals, I think.
Now, whether you could actually do anything useful with a file that
large in an interpreted environment like Octave or Matlab depends a
lot on exactly what it is you are trying to do.  Using for loops to
look at all the bytes individually is probably going to be kind of
slow...

Uh, maybe split(1)?
