RE: rename missing in Text_IO

["Beard, Frank" <beardf@spawar.navy.mil>]

Yes, I realize that, but you're talking about a system dependency
which is a separate issue from the logical operations.  I don't
remember that limitation on VMS, but I haven't been on that OS in
twelve years.

But, if that is the case, then the operation would simply raise 
something like USE_ERROR to indicate a problem.  The developer on that
OS would need to know the system well enough to know that limitation.

And just because it varies doesn't mean it shouldn't be done.  The
Posix binding for VMS had a rename in it.  I hate to keep going back
to the same example, but the same argument can be made, and was made,
for Ada.Command_Line.  It varies from system to system, and doesn't
even exist on some.

Unlike Delete, the legality of Rename is going to vary from operating
system to operating system.  If you rename into a different directory
on VMS, that directory must be on the same physical disk.  With rooted
directories, begin on the same disk is not obvious by comparing the old
and new filespecs.
