Oh, nevermind. I see... the limited size of the memory chunk is based on the zeros on the RIGHT side of the pointer. But the DOS limit was based on the total memory addressable, not the size of each chunk. Why is a 16MB chunk limit such a bad thing?

The existence of the 16-Mb limit is (like DOS's 640Kb) of course the

death knell of the AS/400 architechture. It can only be removed by

the same kind of antics that plagued DOS. The one mistake you

cannot recover from is limitations of the number of 'address' bits.
