as I already said, it depends on your application. and I also add,
it depends on your Perl programming style :-)
a possible way could be:

    $stay_in_loop = 1;
    while ( $stay_in_loop ) {
        ($status, $status_text) = RasGetConnectStatus($hrasconn)
            or $stay_in_loop = 0;

        # ...body of the loop...
            
        $MainWindow->DoEvents();
    }

at this point, you could have for example a 'Stop' button which
can control the loop like this:

    sub Stop_Click {
        $stay_in_loop = 0;
    }

but you may prefer a different approach...
    

cheers,
Aldo
