Hi Roman.

I do understand what packed and unpacked BCD's are ;)
The question was related to some particular unclassified yet
(for me at least ;) case for numbers in range of 0..99. that
is represented in pure binary form and is taken 7 bits to be
stored and carry/borrow operation is propagated to next such
a "number". Looks more like packed 100's number actually ;)
