The question of turning off the calc has been a point of confusion 
for a lot of people (not you specifically Mr. Cordes because you 
wrote it, of course, but I want to clarify it for others who might 
not understand it).  When you press 2nd-ON to turn the calc off, all 
it does is disable the timer interrupts, turn off the LCD, and HALTs 
the cpu right where it is.  When you press the ON key later, it sends 
an interrupt, which simply "unfreezes" the processor and it picks up 
where it left off.  It does the same thing when it turns off 
automatically.  When a program like CalcOFF or KCLock85 turns the 
calc off, it does the same thing, halting and picking up where it 
left off.  Hope that helps!
