getitem

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
