Your point is well taken I could check ASCBFLG,ACBLSAS+ACBTERM and bypass
that address space on second there maybe another way of getting the
information besides going into XMEM


thanks

I think for SSAR I might need to set the AX value to 1 Via AXSET macro
correct ?

Since the question is insufficient, the answer is no. There's more to it. 
And it is not important what service(s) you might use unless you are in an
environment where it is appropriate to do so. AXSET is intended for use
within a cross-memory server address space protocol. That apparently is not
you.

You must not change the SSAR authority within an address space that might be
running any unauthorized code that you do not own. I had mentioned system
integrity ramifications. I did not do so lightly. I'll admit that I do not
know if a "z/OS TCP/IP server" is or is not such an address space.

Regarding 0C4: you might not necessarily get an 0C4. You might, but I think
there are cases where you would get some other failure.
FWIW, is there much value in an implementation that has "I cannot get your
data because, even though the data is valid, it is in an address space that
just happens to be swapped out?"
