This seems like a weird question, but is there a way to UN-initialize a variable?
I'm trying to create stack handling subs (push/pop) but I can't tell how tall the stack is unless I somehow keep a separate index on which elements are actually empty. I was thinking I could use ON_ERROR_PROCEED to determine the stack height of an array, but this only work until I pop the top item, and I don't have a way to tell that item is popped any more. I could just write a known value and know that's empty, but that way I can never use the value intentionally.
I could always have element 1 be the stack height, but that would only really work for a REAL or an INT and feels sloppy.
