<DL>
<DD>allocIVars: allocates the instance variable structure for a new object.  The initial word of this structure is set to class id passed as its argument.  The class also determines the size of the structure allocated.  All remaining contents of this structure are initialized to binary zeroes.<DD><DL>

<DD>Returns a specially qualified version of the zone that automatically allocates all its objects with the internal component qualification, even if allocated with allocIVars: or copyIVars:.

<DD>getPopulation returns a collection all objects allocated in a zone using either allocIVars: or copyIVars: and not yet freed using freeIVars:.  getObjects returns nil if the ObjectCollection option is false.  The collection returned has the type OrderedSet as defined in the collections library, with the ReadOnly option set true and the IndexSafety option set to SafeAlways.
