Hi Monks, I want to share a variable across multiple files. For this, I wrote one module, my_module.pm as below: 
#!/usr/bin/perl

package my_module;
require Exporter;
our @ISA = qw/Exporter/;
our @EXPORT = qw/@my_var change_var/;

our @my_var = (1..10);

sub change_var{
    @my_var = (20..30);
}
1;

I used the module in 1.pl as below: 
use my_module;

print "@my_var\n"; # prints 1..10
change_var();
print "@my_var\n"; # prints 20..30
system("perl 2.pl"); # calling another script
exit;

[download]
The other script 2.pl is as below: 
use my_module;

print "@my_var\n"; # prints 1..10 but expecting it to be 20..30

The changes made to the variable @my_var in 1.pl is not reflected in 2.pl. I want to make the variable @my_var global. Please let me know where I am wrong. Please suggest if I should take any other approach.
