I was  commenting on the meaning of "remember" as well as the choice of that 
verb , as in "the TCBPKF remembers ...", rather than trying to move the topic 
even further tangentially by  discussing the power of authorized programs.  
Sensible actions would not include deliberately changing key system anchors or 
control block fields, but insensible things can always happen until one's 
program is thoroughly debugged whether it is authorized or not .

This is unarguably correct.   Equally, an authorized program can 
change the contents of location 16 (decimal) | x'10' to point not to 
the address of the CVT but to the address of his own private control 
block. 

Implicit in the notion that a program is authorized is the assumption 
that is doing something at least moderately sensible.
