Given everything that has been posted, the conclusion is that your best
chance for keeping things "not visible" is being disabled. You will then
not be interrupted and cannot be canceled. The local lock would prevent
cancels, but not the interrupt cases that Jim Mulder mentioned.

Only by retrying.
If you cannot retry, it is your responsibility not to put things into
registers if they are sensitive in nature (not that that is necessarily
particularly feasible).

Greetings,
I have an FRR that erases sensitive material from storage areas before it
percolates an ABEND. I also want to erase the registers so that any ESTAE
that may get subsequent control cannot see the error-time registers. I
want the ESTAE to see zeroes in its SDWA.
