That depends on who's looking at it, and when, Micheal. PSATOLD is always equal 
to the address of the active TCB. 

So, if you have the address of one of your program's TCBs, whenever that TCB is 
active PSATOLD will point to it. But whenever some other TCB is active it will 
point to that TCB. And that's true whether you've issued RUN or not.
