Getting Data From Visitors

• We know that we can program Perl in a similar way that we can program JavaScript.
• We have variables, arrays, operations, comments.
• We will get to loops, conditionals (if/else) soon.
• We know that Perl can generate HTML pages with the Print statement.
• So, what's the use?
• We can get data from an HTML form, parse it, write it to a file, upload a file, read/write cookies, generate dynamic HTML, and lots more.  Wow!
