[gradsusr] Error in using files in grads binary format

[Jennifer Adams]

The message "Can't open binary data file" means that the file can't be  
opened -- it doesn't mean anything is missing. Check the path.

DSET ^foo.dat  -- GrADS will look in the same directory where the  
descriptor is located
DSET foo.dat -- GrADS will look only in the directory where it is  
running
DSET /full_path_to/foo.dat -- The best way to be sure that GrADS will  
open the file you want

If you are still getting the "Can't open binary data file" message,  
and you are sure the path is your DSET entry is correct, it means  
GrADS doesn't have read permission for the file in question, or it  
doesn't exist.

Also, with GRIB files, make sure you have run gribmap to create the  
index file before opening the descriptor file with GrADS.
