Just make a linked list.  Then it is simple to access th Nth element in the
list.

function varray (list : listtype; n : integer) : nodetype;
var
  temp : pointertype;
  k : integer;
begin
  new(temp);
  temp := list;
  for k := 2 to n do
    temp := temp.next;
  varray := temp.data;
end;

Hope this helps.  In my Comp Sci class, we implemented a linked list.  I have a
Unit that I think is cool.  It includes this function (or something very
similar.  If anyone is interested, I may post it after finals in three weeks.
