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?
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 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
