Hello world

First introduced in the BCPL (Basic Combined Programming Language) programming language, "Hello World" is a program or script that introduces someone to a programming language or for testing a language or its compiler. The code prints the message "Hello World" to the computer screen to confirm that the program works on the basic level. Below is an example of how to print "Hello World!" in Perl.

#!/usr/bin/perl
print "Hello World!\n";
