perldoc -f our perldoc vars Those should help. I think the key line is: "The "our" declaration has no semantic effect unless "use strict vars" is in effect, in which case it lets you use the declared global variable without qualifying it with a package name." Additionally: http://perl.plover.com/FAQs/Namespaces.html In the above a variable tagged with 'our' is a Package Variable.
