 +======Synopsis:======
 +$__getitem__(<array> <item#>) \\ 
 +$__igetitem__(<array> <index#>)
 +
 +======Technical:======
 +These functions are used to fetch data held in the given array.
 +
 +The $__getitem__() function retrieves data based on its item number in
 +the array (counting from zero, the order in which the data was entered).
 +
 +The $__igetitem__() function retrieves it based on its index number
 +(counting from zero, in a sorted order).
 +
 +These functions only affect arrays created with $[[setitem]]().
 +
 +======Practical:======
 +These functions are used to get an item in an array.  The applications
 +for these function should be obvious.  The $__igetitem__() function, in
 +particular, is useful for showing an array's contents in alphabetical
 +order.
 +
 +======Returns:======
 +array item data, or empty string if array or item is not found
