Return or set Arraylist item value (Arraylist class)

Item is a member of the Arraylist class.

This ReadWrite property returns or sets the indicated item in the Arraylist.

For additional description of this method, see Coding considerations for collections.

%currentItem = al:Item( number) al:Item( number) = newItem

%item: A variable of the same type as specified on the %arrayl declaration to contain the value of the specified %arrayl item. Or a variable or value of the same type as specified on the %arrayl declaration to be assigned to the specified %arrayl item.
%arrayl: An Arraylist object.
number: A whole number greater than 0 to identify an %arrayl item by its position in the arraylist. If number is greater than the number of items in the %arrayl, or if it is less than or equal to zero, the request is cancelled.

The Item keyword is not required. For instance, in the For loop in the Arraylist class example, print %alist(%i) is equivalent to:
```
    print %alist:Item(%i)
```
Methods are available to retrieve or seet the first or just the last item in an Arraylist. See FirstItem and LastItem.
