You can create the computer programs in this book using a simple textediting program. I’ve used Notepad throughout this book, but if you prefer, you can use some other program with comparable functionality. (Mac users should refer to “If You Have a Mac” later in this chapter for information regarding working with their computers.)
Once you enter the program into Notepad, you save it. Next, you open it in a Web browser such as Internet Explorer. That’s all there is to it!
