Ok another noob question here...

p:player = new player

players = new tlist
(Now load all players into the players list)
deadplayers = new tlist

function killplayer()
  local pl:player

  for pl = eachin players
    if pl.cond$ = "dead" then
      deadplayers.addlast pl
    end if
  next
end function

Ok here is the question, how many copies of pl do I have? When the player dies I want to move it over to the dead players list. If I do not remove it from the first list which scenario do I have:
(1) Two copies of PL that can be independantly modified
(2) One copy of PL that is refferenced in both lists

Thanks all!

2)One copy of PL that is refferenced in both lists

Type rect
  Field x:Int
End Type
Global list1:TList=CreateList()
Global list2:TList=CreateList()
my:rect = New rect
my.x = 15
ListAddLast list1,my
ListAddLast list2,my
For all:rect = EachIn list1
  Print all.x
Next
For all:rect = EachIn list2
  Print all.x
Next
For all:rect = EachIn list1
  all.x=55
Next
For all:rect = EachIn list1
  Print all.x
Next
For all:rect = EachIn list2
  Print all.x
Next
