index

is the position of the item in the list. The position can be specified as a positive or negative number. By default, index is 1 (the first item). If index is a positive number, then the item is at position index from the beginning of the list. If index is a negative number, then the item is at position ABS(index) from the end of the list. An error condition results if the absolute value for index is zero or if it is greater than the number of items in the list.
