AS/400 Ads - I actually saw one!!!

Paul,

It is, of course, really 65-bit; but we refer to it as 64-bit as the
65th bit is not readily available to applications (including OS/400).
The 65th bit is for tagged storage, and is rather unique to AS/400.
It is used, among other things, to prevent counterfeiting of address
pointers and is tied closely with system integrity.
