I have got the working code which read .cfg file where .cfg file contains an array @cfg and list of hash within it, And the script contain bit of code which read that array @cfg but I am having problem to understand how the reading process carries on bit lost and confuse. Subroutine which carries out reading process looks like this, 
sub ReadCfg
{
    my $file = $_[0];

    our $err;

    {   # Put config data into a separate namespace
        package CFG;

        # Process the contents of the config file
        my $rc = do($file);

        # Check for errors
        if ($@) {
            $::err = "ERROR: Failure compiling '$file' - $@";
        } elsif (! defined($rc)) {
            $::err = "ERROR: Failure reading '$file' - $!";
        } elsif (! $rc) {
            $::err = "ERROR: Failure processing '$file'";
        }
    }

    return ($err);
}
