Hello,

I'm having some problems reading character data from a netcdf file using
PDL::NetCDF.  This is my example nc file (from ncdump):

netcdf testnc {
dimensions:
        recNum = UNLIMITED ; // (3 currently)
        char_len = 256 ;
variables:
        char char_data(recNum, char_len) ;
                char_data:long_name = "some char data" ;
data:

 char_data =
  "some char data 0",
  "some char data 1",
  "some char data 2" ;
}

I will call "get" like this:

$recn = $nc->dimsize("recNum");
$tmp = $nc->get("char_data", [0,0], [$recn, 256]);
print $tmp;

And this is the output I see:

[ 'some char data 0' '' '' '' ]

Why is it only getting the first value?  I've verified that $recn is 3.
 Any ideas?

Thanks,
Brice Lambi
