AFAIK, 32-bit but they need one bit to determine whether they are in 16-bit 
mode or XA 
mode.

Yes!  But not only the larger data width.  Almost everything on the AS/400 is 
better 
than 390 except sheer through-put and clustering (and we are knocking on those 
doors 
already).  390 is a 40 year old architecture -- we're only 20 something.  
Mostly it is a 
case of artificial constraints imposed on the AS/400.

Hardly, Linux is Linux is Linux ..... same-old same-old ....
