A property of netCDF data is that a file created by the interface in
one language, for example Java, should be readable by the API of any
other language, for example Fortran-77.  The latter language doesn't
actually support variable-length strings, so it's difficult to write
an API for Fortran-77 that could deal with attributes that were arrays
of variable-length strings.

Many of the netCDF's limitations derive from the requirement that
Fortran-77 programs must be able to read all netCDF datasets.
