To answer the question someone asked, a large database is one with more than 2^32 bytes. Addressing becomes a major ugly mess at that point. For the end user, perhaps actually at 2^31 if you C, since the offset is signed. I doubt that faking offsets in BCD, or as extents, or whatever is consistent with high performance and bug-free code. Our RAM and disk have outgrown the word size in a decade. The original XT had 10MB, today servers with multiple 2.3G drives, or even RAIDs of 1.3 or 2.3G units are not unheard of. -- bill davidsen, GE Corp.
