First introduced in the BCPL programming language "Hello World!" is a software program or script used to help introduce someone to a programming language, to test a programming language, and/or to test a compiler of a programming language. The few lines of code print the message: "Hello World!" to the computer screen and give the user a basic understanding of how to print something to the screen, compile, and run the program
or script. Below is an example of how to print "Hello World!" in Perl.
#!/usr/bin/perl
print "Hello World!\n";
