i'm just starting to look at the data-structures stuff, so i apologise if any of this is nonsensical.
is there a way to 'select' the empty pointer? (that is, detect that the pointer you are being sent is empty.. and then avoid handing it into a get/set object).
is there a way to determine if a list is empty? i'd like to implement a kind of circular list by sending the rightmost output of the pointer object into a "traverse ..., next" object, without having it freak out if the list is empty.
is there an object for removing a pointer from a list? in the wame way you can append one, without opening the data window in edit mode and manually selecting/deleting it.
