This piqued my curiosity. I investigated:
z/OS 2.2.0
z/OS MVS Programming: Extended Addressability Guide
An introduction to extended addressability
Basic decision: data space or hiperspace
Choosing VIO instead of a data space or a hiperspace
... HLL programs cannot use [data/]hiperspaces directly.
How can it tell? Is there a flag in a control block indicating "HLL"
the supervisor checks and bars use of data/hiperspaces?
What's the definition of a "HLL"?
