I use a module for holding all my config-variables, to share them between the main-script and other modules that offer functions for the main-Script.
When i change the value of a config-variable from the main-script, the functions from other modules will still use the original and not the changed value.
Here is a very simple example of my modules and the main-script:

config.pm:

package config;
use strict;

our $configvariable = 1;
return 1;

sub setconfigvariable {
    $configvariable = shift;
}
sub getconfigvariable {
    return $configvariable;
}

functions.pm:

package functions;
use strict;
use config;
return 1;
sub printconfigvariable {
    print config::getconfigvariable;
}
[download]

Script.pl:

use strict;
use config;
use functions;

print config::getconfigvariable; # 1
functions::printconfigvariable;  # 1

config::setconfigvariable(2);

print config::getconfigvariable; # 2
functions::printconfigvariable;  # 1

Why does the function from die functions.pm-module not use the changed value? What can i do to get the behaviour i expect? Thanks in advance, Enfileyb
