Regarding using the preferred methodI believe its always advisable to have more 
than one solution in a software tool box..Regarding the SSCVT, wouldn't tat 
introduce another variable to be verified ?.The Address contained  SSCTUSE1 
would need to be verified as to the owner of the structure.Was there another 
intention of using ssctuse1 in this function call ?,

Yes, the name/token functions are available to whatever wants to use them 
according to their documented environmental requirements.

What you get back depends on what you put in (obviously if you have not 
done a "create", a "retrieve" is not going to return anything beyond 
return code).

I agree with Tony H's append that many used (and still use) the fields in 
the SSCVT for their subsystem to anchor whatever data they needed.

FWIW, the last 16 slots of the 1024-slot customer anchor table (ECVTCTBL 
points to this area of 4-byte slots, and ECVTCTB2 in z/OS 2.3 or later 
points to an area of 8-byte slots) are available for a customer to use for 
their own shop. IBM and ISVs are expected not to use those slots. They are 
totally up to the customer to manage in whatever way they choose.

I understand a resource manager is the preferred method for handling
specific ending address space termination.
.
To be clear I'm interested in understanding SSI Function Call 08 and 
not a Resource Manager.

Dare one ask why? If there is a preferred method, why would you not want 
to use it? What is the need to understand something that you (as you 
write) shouldn't be using because there's something else that is 
preferred?
