Dear Monks, I wonder if it's possible to create a scrolled widget via the method scrolled, and to let the position of the vertical scrollbar be on the bottom by default. This should look similar to a dos command promt. 
#!/usr/bin/perl -w
use Tk;
use Tk::Pane;

$mw=MainWindow->new();
$mw->geometry("100x100");
$mw->Button(-text=>"START",-command=>\&start_computation)->pack;

MainLoop;

sub start_computation
    {
    $progress=$mw->Toplevel();
    $progress->geometry("200x100");
    $pane=$progress->Scrolled('Pane',-scrollbars=>'oe')->pack(-fill=>'
+both',-expand=>1);
    $text="Computation started...\n";
    $label=$pane->Label(-text=>$text)->pack();
    
    # doing several computation steps
    foreach$step(1..10)
        {
        sleep(1);
        $text.="Step $step finished.\n";
        $label->configure(-text=>$text);
        $pane->update;
        }
    
    $text.="\nComputation finished.\n";
    $label->configure(-text=>$text);
    $pane->update;
    
    $pane->Button(-text=>"QUIT",-command=>sub{exit;})->pack;
    }
