Dave, the question is not so basic as it seems --- at least if you
start thinking about what your user may wish to see as title. I guess
there is a reason why the netcdf people have invented the long_name
attribute... But to solve your actual problem; this can probably be
done with some mystic use of Routine_Info(); Reimar Bauer from Juelich
(r.bauer@fz-juelich.de) is an expert on this.
Cheers,
Martin
