I couldn't resist implementing the `real-life-example':

#!/pro/bin/perl

use strict;
use warnings;

use IO::Handle;
use Text::CSV_XS;

open my $fh, "<", "data.csv" or die "data.csv: $!";
my $csv = Text::CSV_XS->new ({ binary => 1, eol => "\r\n" });
$csv->types ([
    Text::CSV_XS::PV (),        # Server
    Text::CSV_XS::IV (),        # Count
    ]);
while (my $row = $csv->getline ($fh)) {
    my ($server, @data) = @$row;
    $csv->print (*STDOUT, $row);
    }
close $fh;

Note however, the you still got the warnings:

# cat data.csv
CSFDATVM01,,2.55,3.77
# perl data.pl
Argument "" isn't numeric in subroutine entry at xx.pl line 17, <$fh> 
+line 1.
CSFDATVM01,0,2.55,3.77
#

But at least, you reached your goal in a reliable way


Enjoy, Have FUN! H.Merijn
