The variable widget is an array containing all aliases you specify for your
widgets. Vtcl automatically declares it as global (just  look at the
beginning of your program). It also contains the real widgetnames for
example .top17.but5 or so.
So when you want to manipulate a widget from inside of a procedure you have
to declare "global widget" to make the contents of the array named widget
available to your procedure.
