Hi Arlindo,
We're getting closer now...

Then I tried it a second time without the cd....Basically the same result.

Hi Arlindo,
Yeah - this is a tricky bug.

OK - here's the result of trying to get to model_25.gdf

This is the reason why I no longer default to "c:\Progran Files" anymore: GrADS does not handle spaces in file names too well. In this case it is taking "c:\Program" as the filename. Since we are trying desperately get something that works first (then make it robust), let's start GrADS from where the data is:

cd c:\Program Files\PCGrADS19\data
grads
ga-> g2_open model_25.gdf
ga-> g2_verb      <---- this is a separate command
ga-> d g2(tmpprs)

(or else refer to the file as "c:\progra~1\pcgrads19\data\model_25.gdf" as in the old ms-dos days.)

  At this point I am trying to sort out if you have a problem generating the gdf/inv pair, or whether for some strange reason grib2.gex cannot read these on your machine. I'll try your gdf/inv's on my windows box and see what happens.

   Arlindo
