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
