Perhaps you should change those nasty lines of 

print
and make your code easier to read/maintain by either using "here documents" like this:

print <<"END_OF_HTML";  # double-quotes allows interpolation
<html>
...
</html>
END_OF_HTML

or, better, using CGI.pm features to produce the HTML code for you:

use CGI qw(:standard);
print header,
      h1($some_title),
      hr;
# etc...

You can also use templates modules (HTML-Template, Template-Toolkit,...) to separate your code from your layout
