Let's take this bit of code:
int loopb3()
{
  for (n = 9; n >= 1; n--)
   b3 = n;
  return b3;
}

The function loopb3 has a "for..." loop which moves the value of b3 from 
9 down to 0. It does nothing else. The function loopb3 will _always_ 
return 0, which is the final value of b3 after the loop is complete.
