It checks for the presence of reality by seeing if
xis lesser than
x+1. If it is, than all is well and reality is intact. If it is not, than the program informs you that reality has vanished, but, as it's not intact, the program may be incorrect in its assessment.
Of course, it's also good for making sure that your computer isn't dead.
