you are quite correct, the 7030 only had an address space of 24 bits,
quite the same as a segment on the AS/400. How do you in RPG create
and directly access an array with, say, 1000 Terabytes of data? as
you should be able to do in "true" 64-bit addressing. The bus width
was, in fact, 72 bits (including check bits), so the much touted advantage
of 64-bit computing that you transfer twice as much data in one go
was certainly there.
