Those param's come from your query string. You query string is created from your HTML form (or straight on the URL).
<form METHOD="POST" ACTION="/cgi-bin/your_script.cgi" ENCTYPE="applica
+tion/x-www-form-urlencoded">
    <input type="text" name="param_name" >
</form>

if you want to look at your query string as it comes in. 
#!/usr/bin/perl -Tw

use strict;
use CGI;

my $q = new CGI;

print $q->header;
print $q->query_string;
