[gradsusr] Displaying a .nc file

[David Stanfel]

How do I know what variable name will work? I've tried u, v, w, and z and
still only get:

ga-> d v

Error: Variable v not in netcdf file

Data Request Error:  Error for variable 'v'

  Error ocurred at column 1

DISPLAY error:  Invalid expression

  Expression = v

Thanks,

David
