Re: [netcdfgroup] PDL::NetCDF cannot write to existing netcdf files

[Brice Lambi <lambi@xxxxxxxx>]

The docs don't mention an open function and I've tried various things to
find one, but it doesn't seem to exist.  In the examples on the website:

http://search.cpan.org/~dhunt/PDL-NetCDF-4.01/netcdf.pd

They have this example:

  # opening existing file for reading and writing
  $nc = PDL::NetCDF->new ("file2.nc", {MODE => O_RDWR,
                        REVERSE_DIMS => 1});

Which is what I'm doing, but I get the same error when I try to put data
(line 9 is the $nc->put).

Thanks,
Brice
