No. The issuing TCB would be charged for time spent in  the issuing
TCB; it would not be charged for time spent in another address  space
unless there is enclave processing for the CAS. I assume that a  good
chunk of the work done by CAS is an TCB mode, e.g., DYNALLOC,  OPEN.




I said primary above but I meant home.
 
I am confused.  Ed Jaffe says when in Xmem mode the home address  space is 
charged for CPU time (he meant the home's current TCB).  JES2  is always the 
home space in this situation.  JES2 PCs into CAS in  order to do an SVC 26.  So 
JES2 is now the home and primary but CAS is the  secondary.  Then CAS PCs into 
VLF in order to avoid an I/O.  JES2 is  still the home, CAS is now the 
primary, and VLF is the secondary.  Whatever  work CAS and VLF do should be 
charged 
to JES2's TCB, shouldn't it?
