Perl global scope and lexical scope

Nikhil,

P58 of the camel book 3rd edition (excellent summary of scoping rules) says "Although at least two different scopes (lexical and package) are active everywhere in your program, a variable can only exist in one of those scopes".

So the 2 basic types of variable scopes are lexical and package. Package scope is also known as "global scope".

Hope this helps, otherwise, feel free to ask me.
