Perhaps you are mis-remembering the release. I would expect that in OS/390 2.10 there was nothing because 64-bit virtual did not exist until z/OS 1.2. IARV64 was fully documented in the release in which it was introduced. It's hardly surprising that in a staged plan that the initial version contained only get/free and no sharing (GETSHARED was introduced in z/OS 1.5).
