Is that not the official name of the BCP in z/OS?
At least I don't still call it "OS/VS2 Release 2."
Well, it isn't. Program product versions of MVS haven't installed on
top of the free base for decades, and before then the release number
had climbed to 3.8.
No Bill is right. OS/VS2 Release 2 WAS MVS like OS/VS2 Release 1 was
SVS. SVS was OS/360 MVT with Virtual Addresses (SVS was a single 16MB
Address Space with which was divided into smaller areas for the
programs to use, just like MVT). MVS made the program's area into
duplicate address ranges which sat between and shared the low and
high address ranges which belonged to the Operating System.
