In the past (370 pre PLO), CS was the only way to do this function.
While it certainly is possible for IBM to rewrite WAIT/POST to use the PLO
instruction, I certainly doubt that such a code change will occur.
Especially since PLO and CS do not serialize each other's updates!!
The code in the POPs is used - all over the place - to avoid an unnecessary
SVC/PC call. It is completely safe to use.
Indeed. Used heavily by z/OS and nearly every z/OS-based ISV product
I've ever seen.
