Extraptr:

  Extra descriptions, quests structures, etc can be searched and manipulated
using variables of this type. There is no way to declare static structures of
this type in DIL programs. Lists of extra descriptions are easily searched with
the 'in' operator (See below).  Extraptr variables are 'volatile', and thus
cleared whenever there is a possibility that they are rendered unusable.
