Over 20 years ago for me. Never looked back.

It has been 30 years since I saw a program that actually required V=R to
run successfully, and that was only for specific OLTEP test programs
that dynamically modified CCW chains.   believe that device being tested
no longer exists.

I believe most installations set IEASYSxx REAL= to 0 a long time ago,
and never looked back.  If they did not, then they should.

As to keys 10 through 15, I don't see a great need for using them.

Regards,
Greg

This still seems to be supported in z/OS 2.2. Does anyone need to run a
program V=R in today's world? I'm just curious because this support seems
to be a "waste" of protect keys 10 through 15. Of course, if those keys
were "freed up", what could they be used for?
