These lecture notes are here for archival reasons. I no longer teach Perl.
As such some of the latest Perl innovations are not present. The notes refer to Perl 5.001

Detail on more modern Perl maybe found at:
One of the most popular uses for CGI programs is to process information from HTML forms. This chapter gives you an extremely brief overview of HTML and Forms. Next you see how the form information is sent to CGI programs. After being introduced to form processing, a Guest book application is developed.
