reading hdf format files

[Lee HanSoo]

Hi grads users

I have two hdf files and a fortran program to read the hdf files.
When I tried to read one of the files with the fortran program, I have
errors from the compiling process of the fortran program about hdf
library.
But I have hdf library installed corrently since I can handle with the
other hdf file in GrADS and with hdfdump and ncgen to make .nc file.

I attached hdfdump info. of the file below. It is strange also that one
file is ok with hdfdump while the other gave just header info. without
data. You can see it below. So one of the file was ok to make .nc but the
other had an error to make .nc file.

I am working on Linux RH9.0 with GrADS 1.9b4.
Thanks for any help.
