Thank you Kevin. That is precisely what I was looking for.
In my case I am using this to make viewing of certain types of data
and calibration files easier. These files should be opened in 'text-
mode', except with out wrapping. Setting a mode hook is therefore not
appropriate. This seems like a better solution that creating (or
finding) a 'data-mode'.
Thanks again
