I did not yet fill out the registration for just that reason. Thanks
for the chapter hint.
I would like to thank again to everybody who sent me a copy of the redbook.
I'm surprised that so many people wanted to help me. I'm very glad of
your help.
For those, who didn't help me, but going to: please *don't* send me any
more copy of the redbook. Have mercy on my mailbox vbg
Again,
As we know, MSU value in z/990 was approx. 90% of technical MSU.
In z9 it was 0.9 * 0.9
What about z10 ?
Is it again 10% less than previous generation ?

Gentlemen,
I stand corrected - it is 90%, without approx.
