Brian,

>Is there ANYONE there who might have time to look at the gribdec decoder?

Unfortunately, the only person here that does McIDAS support is me.

It would help if you gave me access to:

o the grib file(s) that you are decoding
o where you got the grib file(s) (you sent me this before, but this would
  speed the work)
o the environment in which you build/run gribdec.k (e.g. platform, OS, compiler
  versions, etc.)
o an example plot or two of fields that are "funky"

I will then build gribdec.k linking against the Undiata v2002a+ distribution
of McIDAS and decode into GRID files and verify your results.

>Please let me know if anybody will have time to help me with this.

I will try to get to this today.

>P.S. - Happy Turkey Day!

You too.
