Brian McCloud un giorno parlo' di Extended Registers....
 BM> you would consider the "best" way...  Here's a few ideas for moving the
 BM> high word of EAX into AX:
 BM> 1.      SHR     EAX, 16
 BM> 5.      SHRD    EAX, EDX, 16    ; EDX can be changed to another
[+ others..]
What can be the meaning of 'best' ? I say the best is the fastest,
or the one which uses less registers...
In the first case we can count the cycles of every method...
