The state of the boolean is not kept in a variable.  The code I wrote 
actually changes the register to turn the light on and off.  A boolean 
is not necessary to keep track of the light.  Either the damn light is 
on or off.

You can tell by looking at the LED.  Is_On is a function to check the 
state of the register in question.

Enough... We're in the team ada room.  I have been explaining how Ada 
works.  I don't particularly care how C++ works.
