So Perl is working, and you are working with Perl. Now for something more interesting than simple printing. Variables. Let's take simple scalar variables first. A scalar variable is a single value. Like $var=10 which sets the variables $var to the value of 10. Later, we'll look at lists like arrays and hashes, where @var refers to more than one value. For the moment, remember that Scalar is Singular. If weird metaphors help, think of lots of scaly snakes at a singles bar. If that didn't help, I apologise for putting the thought into your mind.
