Chapter 16. CGI and Perl > Scripting with Perl

Scripting with Perl

Like all scripting languages, Perl has a set of statements, variables, functions, operators, and other typical language features. However, because Perl was designed to work with data to be passed between clients and servers, it has special commands for handling data to be stored and retrieved from the server. Variables in HTML forms can be passed to a Perl script, and JavaScript’s main role lies in preprocessing the variables in the forms.

Getting Started

You will need a hosting service that provides you with access to CGI and a Perl interpreter. The examples used for this book were done using JTLNet as a hosting service (www.jtlnet.com), and you will find them to have everything you need for simple access for CGI. If you already have a hosting service, it should be capable of showing you how to set up and use CGI. If your service does not allow CGI, get another hosting service that does. You can find plenty of high-quality services for less than $8 per month.
