Thanks Robb,

I already had the File action set up to get the raw grib data, but I wouldn't 
have thought
of using the argument to gribtocdl. The grib data won't start for a while 
today, so I
won't get to try this until next week. Tuesday is the first day I can try it, 
but I'll let
you have a working cdl file I hope.
