RE: Explaining single level store to non i people

Hans,

I could have SWORN Dr. Frank said that to go the 128-bit it was
basically "flipping a switch" but there had to be a business need ?

Bill: Don't forget that, on the iSeries, the 64 bits are used to address
everything on the system. That's basically what the single-level store
means. So, out of a 64-bit address, some of those bits address the
object,
other bits address a location within the object.

I don't know what kind of work would be involved for addressing on the
iSeries to go "above the line" within the constraints of the
single-level
store. But I would guess that if it were easy, it would have been done
long ago.

Cheers! Hans
