TCBPKF remembers the original storage key set by the system in the same sense that general register 3 remembers the number X'5AD' after you load that number into register 3; i.e., the remembering lasts until something changes the value being remembered . An authorized program can cause TCBPKF to remember something different, either by accident or design.

I'd hardly call that remembering, and TCBPKF need not match the key just prior to the MODESET KEY=ZERO. -- Shmuel (Seymour J.)
