in reply to Undefined subroutine

In order to use OO to it's fullest, you will need to create a constructor ('new' method) and then you can instantiate an object with your class: 

package Test;
...
sub new 
{
    my $self = {}; 
    bless $self;
    return $self; 
}
...

use Test;
my $test_var = new Test;
$test_var->Prt("This is a test in the Mod\n");

You should also take a look at perltoot which has some more details about how to create constructors.

Update: You should make sure that your module does not have the same name as an already installed module, or else you can cause yourself some unneeded confusion.

Update: why do I need to use OO stuff? You don't need to use the OO stuff. Your statement was 'Any help would be greatly appreciated' and I was simply offering another solution. Sorry for the confusion.

    I'll give this a bash, but I can't help wondering why I need to use OO stuff though. I just want to use a module straight like I would with 
    #! /use/bin/perl
use strict;
use Term::ReadKey;

ReadMode( "noecho");
print "Enter pwd please :";
chomp (my $pwd = <>);
ReadMode ("original") ;
print "\nYou typed $pwd!\n";

    where ReadMode is a subroutine in the Term::ReadKey module.

    Isn't a Module != Object?

      Yes, you are correct, a module is not an object, but you can use a module to instantiate an object. e.g. use MyMod; $object = new MyMod;
