Owen,

The ASCII files would be HUGE.  Given your message, I started digging
into the grib decoding code to see if I could get this to work.

Again, dumping the values into ASCII would create absolutely HUGE data
files.

>Is this program still available?

I took a quick look and did not find it.  I would dig for it if I
thought that this is what you really need, but I don't.

>Thank you in advance for any info. you can send my way!

Hopefully, I will discover something simple to fix/alter in the grib
decoding software of McIDAS that will then allow for decoding of the
1x1 degree AVN grids.  As soon as I determine if this is possible, I
_will_ let you know.
