Hi,

Thanks for the quick replies. There's a mistake in the constructor in line 10. Must be $proto and not $package.

The code I posted is not the code of my complex program. It is an equivalent piece that is in a symanticly point of view the same. I now tested it and it did not work. I changed flattening into references and it presented the same results to me: I changed the first line of config.cfg to option1=HASBEENCHANGED while sleep(15).

FILE 'test.pl': 
use strict;
use Foo;

my $object = Foo->new('admin');

$object->show_config();
sleep(15);
$object->change_config();
$object->show_config();

FILE 'Foo.pm': 
package Foo;

use strict;
my $config = _parse_file();

sub new
{
   my $proto = shift();
   my $status = shift() || 'normal';
   my $package = ref($proto) || $proto;
   
   my $self = { status => $status };
   bless($self, $package);
   
   return $self;
}

sub change_config
{
   my $self = shift();
   return unless $self->{status} ne 'admin';
   $config = _parse_file();
}

sub show_config
{
    foreach (keys(%{$config}))
    {
        print "KEY: $_\tVALUE: $$config{$_}\n";
    }
}

sub _parse_file
{
    my $filename = 'test.cfg';
    my %temp;
    open(CONFIG, "<$filename") or die "can not open!\n";
    while (<CONFIG>)
    {
        chomp($_);
        my ($key, $value) = $_ =~ m/^(\w+)=(.*)$/;
        $value ||= '';
        $temp{$key} = $value if ($key);
    }
    close(CONFIG);
    return \%temp;
}
1;

FILE 'config.cfg': 
option1=value1
option2=value2
option3=value3
Output: 
KEY: option1    VALUE: value1
KEY: option2    VALUE: value2
KEY: option3    VALUE: value3
KEY: option1    VALUE: value1
KEY: option2    VALUE: value2
KEY: option3    VALUE: value3
