"my" declares a variable that exists within the current scope and is unreachable from outside the scope. So a "my" declaration in one package cannot be reached from another package. "our" is identical to "my" except that you *can* reach that variable from other packages. A "my" declaration inside of a function just limits the scope and lifetime of the variable to that function. -- Chris Howie http://www.chrishowie.com http://en.wikipedia.org/wiki/User:Crazycomputers
