OFFICIAL GUIDE TO PROGRAMMING
WITH CGI.PM
Example Scripts from the Book
Here is the source code for all the examples from the book. Each example
is listed by chapter, listing number, and page number. You'll find two links
for each example. The top link will run the script so that you can try it
out for yourself. The bottom link will take you to the source code for the
script. You may read through it online or download it to your own machine.
There are several ways to download a script's source code. One way is
to choose File->Save As... from the browser's menu when the script
appears on the screen.
Another way is to simply cut and paste from the browser window to your favorite
word processor. Some browsers also offer you the ability to save the contents
of a link by right-clicking, control-clicking, or by command-clicking,
depending on the browser software and the type of computer you are using.
There are no restrictions on your use of this source code.
Feel free to redistribute it, modify it for your own purposes,
or incorporate it into your own projects. Have fun!
