Also in the docs it mentions:
If this file exists and you want to write to it, prepend the name with
the '>' character: ">name.nc"
So with this code:
my $nc = PDL::NetCDF->new(">testnc.nc", {MODE=>O_RDWR,REVERSE_DIMS=>1});
I get the same error:
MODE set and testnc.nc starts with >: suppressing > at ./testme.pl line 7
Cannot write read-only netCDF file testnc.nc at ./testme.pl line 9
