The S360 PrincOps didn't say anything about serialization (of course),
but I figured I'd look for something like a M91 Functional
Characteristics book.  I found the "IBM System\360 Operating System
Guide to Model 91 Support":
        http://bitsavers.org/pdf/ibm/360/C28-6666-0_360-91_OSsupport.pdf
which does by golly on page 7 refer to
        BCR M,0    where M not= 0
So I didn't mis-remember!

(Of course, I'm not all that current either.  But that's another kettle
of fish.)
