In UniData there is no such animal as a distributed file. You only have the
choice of static hashed or dynamic hashed.  Dynamic files in UD are how you
get past the 2 gig limit because the UD implementation of dynamic files
breaks the file into different pieces.  How many pieces and what goes into
each 'piece' is decided by the hashing algorithm (no control by the user).

In UniVerse dynamic files are much the same as UD with the exception that
they don't have different 'pieces'.  That's why in UV dynamic files do not
get you past the 2 gig limit.  UV has a different animal called a
distributed file.  In a UV distributed file the number of pieces and what
goes into each piece is set by the user.

Dynamic files are no help in your situation, they are 2GB or 64-bit just
like hashed files. You need either 64-bit or a DISTRIBUTED file.  [I think
this kind of file is called 'dynamic' in UniData, just to make things
confusing!].  A distributed file divides the data into several portions
based on the record-ID. There have been several discussions of UniVerse
Distributed files on the list in the past year or so, check the archives.
