Virtual-storage accessibility is an issue about which the Systems Architecture
team was often asked, by customers, ISVs, and IBM developers.
At a SHARE presentation in 2009, I dragged out my FrameMaker instruction
template and designed the IS IT SAFE (IIS) instruction in about 5 minutes. IIS
Paul,
There is a major issue with just using CLC or OC to verify the address,
at least in my situation.
I can't just set up an exit to trap a soc4 (in my case, using a VSE EXIT
PC) because I am running within someone else's environment. They may
have already, such as in CICS, set up their

Like LRA or TPROT or other similar instructions do

Such instructions are prudently designed to detect and report
attempted unauthorized access. Are you
TPROT is not definitive; LRA can tell you, but is privileged and still
has some limitations.

Why?
What would you code do differently?
Just recover from the 0C4.
You could use VSMLOC, but that won't help you with key mismatches. And, of
course,
We created a subroutine using ESPIE to return none/read/write access.

Why not set an ESTAE and field the S0C4?
Valid for read or valid for tor store?
Hi
What do you guys use to check if a virtual address is still valid to avoid a
S0C4?

To address Peter's question about "hyphens", we have added a
sentence to the OPTABLE column description as follows:
A dash between levels indicates a range of consecutive levels,
first to last, and a level with a trailing dash indicates that
the instruction has been available since that level
Incredibly useful!
Please let the entire Hursley team know how much we appreciate this
effort...
