Create download button using perl CGI

Hi, I want to insert in a page a .html button that - once it is clicked - opens a save file dialog box by using perl CGI .

I know that to create a link to do that I've done :

print $cgi->p ( { -class => 'linc' },[ $cgi->a({-href=>'http://server/doc_name.doc'},'doc_name')]);

I want to do something similar for a download button
