# untested!

use CGI; # the standard way of using perl to write web pages

my $cgi = new CGI; # creates a new object to use

print $cgi->header; # prints out your basic http headers

my $continue = $cgi->param('continue'); # get the value of the "continue" parameter passed to your script

# print some HTML here...

print "<A HREF=\"$continue\"><B>Continue</B></a>"; # some people use CGI methods to print out HTML, but I am happy doing it raw
