((SIZE ** LENGTH) * SCALE)  is  ((size^length)*scale

Note, in the comment ** was used since in C ^ is xor, and not power,
thus using ^ in C source can be confusing.

So if size is 36, length is 8 and scale (which I am not sure what it is)
is 256, then:

36^8 == 2821109907456 * 256 == 722204136308736

Since 2^64 is 18446744073709551616 so ((36^8)*256) is well below 
this level.

Jim.
