Dave,

Hmm...  Since you did not have GRID decoding turned on before, they
should still have been turned off now.  Since they somehow got turned
on, it means that I have some investigating to do.  To answer your
specific question, however, the procedure is:

<login as 'mcidas'>
cd workdata
decinfo.k SET DMGRID INACTIVE

I just did this exact procedure for you on weather.

McIDAS decoded GRID files are BIG.  The total amount of disk space needed
to decode all model output is well over 1 GB per day.

No problem.

Count on at least 1 GB for GRID data per day.

No worries.  It looked suspicious.

OK.
