These are general CS terms and easily googled: http://en.m.wikipedia.org/wiki/Scope_(computer_science) http://www.geeksforgeeks.org/static-and-dynamic-scoping/ Perlglossary is from the Camel book, and as such binding for Perl terminology.

A local just gives temporary values to global (meaning package) variables. It does notcreate a local variable. This is known as dynamic scoping .	[reply]
