   Assuming each individually bit can be addressed, scanning would not even be   
   necessary.   
      
   1 Hole plugged.

   True, but ok... a more efficient coding could even plug this hole.

   True same as above.

   A 1 bit cpu can solve it.   
      
   Why not a 16 bit cpu.   
      
   Pretty simply really, a sliding register etc.

   Don't do that ;)   
      
   Add some nice error checking :)

   So far all holes plugged... bring on them holes ! :)
