I've heard of this. And that the "magic SVC" did extensive checkinf

Bot that it was possible, in principle, to fool it.
But why? couldn't it just perform the equivalent of

It used to be the case that since ISPF didn't run authorized that it was
impossible to directly invoke authorized utilities from within ISPF
