As others have said, the Customer Anchor Table has fullword slots assigned to individual customers or ISV's on a one-per-company basis. Quoting Peter Relson's 1996 email "Once assigned, that slot is yours 'forever' and will never be reassigned to someone else. You can do with it as you want.". It would be interesting to know how many are actually assigned.
As it is in 31bit common storage anchored by ECVTCTBL its easy to get to (six instructions or less) and saves having to use system level name/token services. I used it to anchor some in-house control blocks after I discovered some ISV software using the CVTUSER field.
