That bit of code worked for me under Perl 5.6.1 with an older version of the CGI library. However when I ran it under 5.8 with new CGI library, I get the warnings messages. It turns out that you need to define the 'action' for the form to get rid of the error message. Could be a bug in the new version of CGI module, but then again you should really define the action to be taken when submitting the form.

#!/usr/bin/perl -w

use strict;
use CGI qw/:standard/;

print header();
print start_html("This is a test");
print start_form(-action=>"/cgi-bin/test.pl", -method=>"GET");
print end_form();
