Give me an example name of the GFS file you are opening.

Subject: [gradsusr] Not all variables plotting

Hi

I've upgraded my laptop to Opensuse 11.3 but am having some trouble accessing 
grib2 data using the latest version of OpenGrADs.

I've put OpenGrads Version 2.0.a8.oga.1 for Linux on this machine.

>From the Grib2 data I make a ctl file using g2ctl v 0.0.4o - this seems fine.
gribmap -i $datadir/gfsgrb2.ctl works okay (well makes a plausable .idx file).

In grads I open the gfsgrb2 file okay, and it plots winds and some variables 
okay. 

However, for others I get the message:
ga-> d apcpsfc
GRIB2 I/O error: message not found
Data Request Error:  Error for variable 'apcpsfc'
  Error ocurred at column 1
DISPLAY error:  Invalid expression 
  Expression = apcpsfc

I can get it to work using an old (v 2.0.a5) grads executable, but the latest 
v isn't happy with around 50% of variables.

One thought is it a problem with the undef setting? 

I note my .ctl file has undef 9.999E+20 which isn't the standard anymore. 

Any ideas?

James
