[gradsusr] GRIB2 All Undefined Values

[Ricardo Hallak]

Hi Charles, 

I can't see anything wrong in your .ctl. 
So, please, check if there is not a dot between the word "master" and "grb" in the file. If it really has, please, correct the .ctl and rerun gribmap.

> Hello All,

> I am a fairly new user of GrADS. My setup includes: GrADS 2.0.2 on
