Hi Monks,

I'm currently stuck at a very simple problem it seems, but I don't get it done. Maybe I'm just confused atm, I don't know. But enough talk, here's the problem:

I'm trying to share a variable %default_settings (a dictionary or assoc array to be precise) between 2 perl files. The file that is executed by the user is called 'app.pl', the other file is called 'settings.pl'.

I do 'use strict' in my code and I'd like to continue doing so. I'm using perl 5.8.8 on Linux, btw. Here's the files (relevant sections): 

##### start of app.pl ##### 
#!/usr/bin/perl
my $settings_file = "./settings.pl"; 
use strict;
our %default_settings;
require $settings_file;

# ERROR IS IN THE NEXT LINE: %settings is empty (because %default_sett
+ings is empty)
my %settings = %default_settings;
##### end of app.pl #####

##### start of settings.pl ##### 
%default_settings = (
    $verbose => 1,
    $debug => 0,
    $help => 0,
    $game => "etqw"
);
##### end of settings.pl #####

That's it. It seems that require in Perl isn't equivalent to #include in C. In C, this works (and is what I want to do): 

##### start example #####
spirit@threat:~/develop/example$ cat hello.cpp

#include <stdio.h>
#include <stdlib.h>
#include "var.cpp"
int main(int argc, char *argv[])
{
  printf("Hello world!\n");
  printf("I'm %i years old!\n", var);
  return 1;
}

spirit@threat:~/develop/example$ cat var.cpp

int var = 3;

spirit@threat:~/develop/example$ g++ hello.cpp
spirit@threat:~/develop/example$ ./a.out
Hello world!
I'm 3 years old!
##### end example #####

My problem is related to namespaces if I'm not mistaken. I searched a bit and a thread on another forum suggested to use 'our'. That's what I do in the code as you can see, but I obvisously managed to mess it up anyways. Ideas?

Thanks in advance and 'Hello' to everyone around! (This is my first post here) -
