We use heap block to store the handles to the objects contiguously rather than have saate block for each handle and link them together This saves uo memory overhead and reduces the number of Memory "Manager calls It also reflects the assumption that insertions and deletions into the middle of the list be infrequent. as these could be more inefficient than with linked scheme We expect that elements will normally be added to the end, and probably not removed at all, or not very often Superclass ObjHandle Sequence Source file Struct Status Core Instance variables handle TheList Points to the memory block containing the h ...
