I have read that an access type parameter is always copied in even when
the parameter is an out parameter and that this is so that the access type
is not undefined which can cause problem. Could someone please elaborate
on this? It is my thought that access types are initialized to null when
not explicitly initialized so that an uncopied access type going into a
function will only result in the formal parameter being initialized to null.
Maybe I'm being picky but I like to learn things thoroughly.
Thanks.
Ron
