Two questions about the List

[Armoured]

1) If I use "Delete Element" to eliminate an item from a list the memory occupied by this item is immediately released to the system?
2) The memory used for the items in the list come from the stack of the exe?

Thanks

1) You can read about the memory management of linked lists here: https://www.purebasic.fr/blog/?p=8
2) The memory comes of course from the heap and not the stack.
