Re: Fixed problem

Steve,

I was extremely busy yesterday so I couldn't remember the syntax for the
multidimensional arrarys, etc. I modified the the example you sent, using
the 1st dim as unlimited, thats what my understanding was yesterday.
The original example is dependent on the manner that perl stores
strings in arrays thats why the padstr function is used so one gets
what one expects. Sometime the API don't work as expected. Don't
ever think I will not answer a question, sometimes I need time to get to
the problem.

  use NetCDF ;
  $ncid   = NetCDF::create("demo.nc", NetCDF::CLOBBER ) ;
  $dimid = NetCDF::dimdef($ncid, 'recNum', NetCDF::UNLIMITED);

      }

  #NetCDF::varput( $ncid, $varid, [3,2], [2,7], \@names ) ;

  NetCDF::close($ncid) ;

        
# pad str to correct length
sub padstr
{
( $str, $len ) = @_ ;

my( $size, $i ) ;

$size = length( $str ) ;

for( $i = $size; $i < $len; $i++ ) {
        $str .= "\0" ;
        #print "$str,\n" ;
}
if( $size > $len ) {
        print STDOUT "String length is over $len chars long:\n $str\n" ;
        $str = substr( $str, 0, $len ) ;
        #exit 0 ;
}
return $str ;
}
__END__

And this is what I get from ncdump:

ncdump demo.nc
netcdf demo {
dimensions:
        recNum = UNLIMITED ; // (10 currently)
        stations = 10 ;
        strlen = 10 ;
variables:
        char station(recNum, strlen) ;
data:

 station =
  "abcdef",
  "ABCDEF",
  "A",
  "B",
  "C",
  "D",
  "E",
  "F",
  "G",
  "H" ;
}
