What does this mean?
Nope, that's unshift(). shift() removes the first element from the array, while unshift() adds a element at the front of the array. push() and pop() add and remove an element from the end of the array. shift() without an array works on @ARGV if outside of a sub, or @_ inside a sub. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
