The above message contained the following:

> compatible. Is this right?

No. You do not need to know how the netCDF file was created in order to
read it. The elements of an array in a netCDF file are always stored in
the same order as the elements of the in-memory array -- regardless of
whether the C or Fortran API is used to access the data. The innermost
(i.e. most rapidly varying) dimension is always the innermost dimension
in both C and Fortran.

I suggest that you carefully examine the examples in the email message
that I previously referenced.
