in thread Tk question

'my' declares a variable within the 'current scope' - if that's in a sub (or any pair of braces),it's gone when you exit the sub. If, on the other hand, it's in the 'main body' of your code, it's global. That is generally a Bad Thing.
That makes it sound like using "my" at global scope is a Bad Thing. Shurely not?

    Yes, I think globals are a Bad Thing generally - not So Bad that I don't use them {g}, but it'll only ever be a couple ($dbh and $cgi, generally). I try to only use globals if it makes things more stylish, or efficient, or pretty. In a case like this, where it looks he's trying to make *every widget* global, that's almost definitely a Bad Thing, and is probably contributing to some 'code spaghetti'.

    Cheers, Ben.
