Remarks

Deleting elements

One-dimensional array: array size is set to 0. The array is not freed: new additions can be made without reallocating the array.
Two-dimensional array: only array rows are deleted. The columns are kept. Therefore, <Array>.AddLine can be used after <Array>.DeleteAll.
Associative array all elements of the array are deleted.
Queue all elements in the queue are deleted.
Pile: all items in the stack are deleted.
List: all list items are deleted.

Note: To reset array elements to 0 (or "") without changing the array size, use the VariableReset function.

Elements of Queue, Stack and List variables cannot be deleted.

Miscellaneous
