The button is defined by $x, in the sub make_slot 
 $goSlot[$x] = $slot->Button()

[download]
so keep track of $x.

What are you trying to do with the button tracking?

    I'm trying to figure out how to keep track of $x. I want to be able to pass a unique serial number that is associated with the start button. So, for example, if slot 1 contained serial number 01234567, I want to be able to process that serial number if slot 1's start button is pressed. I'm pretty new to perl so I'm kind of floundering here. Thanks for your help.

      You could pass the slot number to the compute call: 

          $goSlot[$x] = $slot->Button( ...
        -command => sub { compute($x) },

      Then, in the compute sub, you can access @sernums, @partnums, etc. e.g.: 

      sub compute {
    my( $slotnum ) = @_;
    print "sernum=$sernums[$slotnum], partnum=$partnums[$slotnum]\n";
}
