Peter,
I still have no exact idea what both instructions do (waiting for the
book of books) , but your stmt
>> Both LBEAR and STBEAR are created for OS's other than z/OS
let me hope that both where for ALSO not for the little stepbrother z/VSE.
And now I can even visualise "constructive" use for my (wrong) idea of
addressing the location (and not the hardware as Ed pointed out).

Could z/OS use them constructively? Possibly. If by "constructive" we
positively balance functional benefit over performance cost.
Could an application use STBEAR constructively? Possibly. Probably more likely
to be of constructive use if the OS itself uses LBEAR and STBEAR.
