I am working on an app for win NT4 with Tk with plans to export it with perl2exe. I have mulitiple windows that I would like to close with a exit button. I was thinking one sub with a var would be the shortest way of writting the code. (ex: 
sub close_win(var) {
     var->destory;
     }
button(-command=>\&close_win($thiswindow))->pack...

[download]
...) I can't seem to find how to write a function and pass a variable. Any suggestions on where to find the proper way of writting a function?
