Hi nisha, Below is a sample code that calls a ReadConfig() from the module. This should get you started in your work.

package Skywalker;
require Exporter;
@ISA = qw(Exporter);

use strict;

our @EXPORT = qw(ReadConfig);

sub ReadConfig {
    my ($file) = shift;
    warn " --- going to read config file: $file ---\n";
    # more steps here
}

1;

now the calling file itself

#!/usr/bin/perl
use warnings;
use strict;
use Skywalker;

ReadConfig('/tmp/simple.cfg');
[download]

output:

perl walktest.pl 
 --- going to read config file: /tmp/simple.cfg ---

Hope this helps. Good luck
