Problem
mov ax, 6
mov dl, 5
mov ecx, edx
add eax, ecx
mov dx, al
A. What is the value of al before the final move?
B. How many bits are in dx? What about al, ah, and ax respectively?
C. Is this a valid series of instructions? Why? If so what is the final value of dx?
D. How could I get the high order 16 bits of a 32 bit register? What asm instruction would I need if I wanted to get the high order 16 bits of eax?
