Art If you know that you are running on a z/Architecture machine, then you could use the STore Facility List (STFL) instruction to help you decide what is available or not (though this does lead to dual- pathing your code which you may not want to do)
STFL is priviliged but z/OS does issue it and leaves the data at real address 200 where you can inspect it. If you are the latest hardware then you can use STFLE which is an extended version that is also a problem state instruction. The facility bits that these instructions store are all described at the end of Chapter 4 in the latest Principles of Operation.
