[gradsusr] DISPLAY error: Invalid expression

[Jeff Duda]

Since the dtype is netcdf, you need to add the units entry to the var
entry.  See this section of the gridded data description file documentation
<http://www.iges.org/grads/gadoc/descriptorfile.html#VARS>, specifically
the part labeled "units (dtype netcdf...)" to see how you should handle
that.  You'll need to do an ncdump -h on your data file to figure out the
order of the dimensions.
