Call Insert to add a component at a specified position in the list, shifting the item that previously occupied that position (and all subsequent items) up. Insert increments Count and, if necessary, allocates memory by increasing the value of Capacity. 

The Index parameter is zero-based, so the first position in the list has an index of 0. 

To replace a nil (Delphi) or NULL (C++) reference with a new component without growing the array, set the Items property directly.
