Parameters

Type	Name	Description
int	index	The index of the first element that will be shifted up.
int	count	The number of elements to insert.

Remarks

Right-shifts elements in the list so as to create 'free' slots at the beginning or in the middle.

Copies the last element of this list to an index. Decrements the length by 1.

Declaration
