[gradsusr] Problem with running sdfopen in windows batch mode

[Garut Lama]

Dear all,

I'm using grads 2.0.a9.oga.1 installed in the c:\ drive of  Windows XP. I
wrote a batch script(.bat) to generate graphical outputs from
http://nomads.ncep.noaa.gov:9090.
The script works if it is   placed in any folder in the C:\ drive but fails
when it is  run from a pendrive, external drive , d:\ drive etc. Among the
content of the script is:  grads -blc "run script.gs"

The following messages were displayed on the execution of the script from an
external drive:
