Here is another way of looking at this:

IDL> myObjArr=OBJARR(3)
IDL> myObjArr[0]=Obj_New('idlanroi')
IDL> Help, /HEAP
Heap Variables:
# Pointer: 0
# Object : 1

<ObjHeapVar21> STRUCT = -> IDLANROI Array[1]

IDL> OBJ_DESTROY, myObjArr
IDL> Help, /HEAP
Heap Variables:
# Pointer: 0
# Object : 0

Cheers,

David
