Im new to -tk and I have written the following fascinating program. 
  
 #!/usr/bin/perl -w
    use Tk;
    use strict;    
    
    my $mw = MainWindow->new; 
    $mw->Label(-text => 'Number')->pack;
    my $nmbr = $mw->Entry(-width => 10);
    $nmbr->pack;  

    
    $mw->Button(
        -text => 'Print',
        -command => sub{do_print($nmbr);}
        )->pack;  
          
    
    MainLoop;      
    
    
    sub do_print 
    {
        (my $nmbr) = @_;
        my $nmbr_val = $nmbr->get;
        print "Printing number $nmbr_val\n";
    }

The program open a window with a entry box in which it is possible to put in values. The value in the box is printed in the console when the button "print" is clicked. Now I wonder if it is possible to preset a default value in the entry box so that there alredy is a value in the window when the program is started. (Which could could then be changed to something else.) Thank you for any help.
