In any case, if you use a module, you get the power of the previous work and have an interface to reach that functionality.

In this chapter, we will talk about organizing code in modules and using them in a program.

Let us create our first module and let's take the simple task of adding numbers that we were exploiting in earlier chapters, for example, in Chapter 2, Writing Code.

So, we have an add function for adding up two numbers and the code that uses it:

sub add($a, $b) {
return $a + $b;
}

my $a = 10;
