Yes, although I suppose its possible to break the one file into several
smaller data source files. They are legal documents and the bulk of the
fields contain names, addresses, relationships of persons named in the
document. I could probably normalize this a bit. I still am suprised Word
limits the data source to 255; I expect that is because it holds the values
in an array so it can show the "merged" documents directly in the Main
Document prior to performing the actual merge process to a final document.
