[gradsusr] Opening and extracting grads file generated from fortran

[Jeff Duda]

Your control file has time templated.  The time index defaults to 1 when
you first open the control file.  So check if the file
1981/mld.19810101_0000 exists.  I guessed the name of this file based off
of the DSET entry in the control file (which tells Grads where to look for
the data files) and the TDEF entry.  Since the path I just mentioned seems
relative, make sure you run Grads from the directory that contains these
files.  Otherwise the control file will not find the data and you'll get
that error.  So check on that first.
