I have put this back to "unsolved" status-----because 2 solutions (including mine) have some issues when fields are empty.
A fix that's in my head is to first preprocess the files and put a word (eg "none") in place of the empty fields. While my head tries to do this, I fully expect an AWK wizard to jump in with something more elegant....
