Perl is a programming language. One that I am quite impressed with. Perl is not an application program like "Microsoft Word". What other programming languages do you know? I would recommend trying to implement some program that you know works in another language into Perl. Make an attempt and you will get some help.
Update:
Are you able to run the classic "hello world" program? Download this file as "hello.pl" and from the command prompt, type: perl hello.pl That should work on Unix or Windows.
#!usr/bin/perl
use strict;
use warnings;
print "Hello World!\n";
