Dear Zion Wang;

I regret to inform you that the Fortran-90 interface of the netCDF
package doesn't support environments where real and doubleprecision
values are both 8-bytes wide -- and we have no immediate plans to
address this situation.

Workarounds include the following:

    1.  Not using the Fortran-90 interface (as you saw, the Fortran-77
        interface works OK in this situation);

    2.  Modifying your code -- replacing the use of real values with
        doubleprecision ones where appropriate.

Good luck.

Regards,
Steve Emmerson   <http://www.unidata.ucar.edu>
