一、 补全下面的程序，统计F000:0处32个字节中，大小[32, 128]的数据的个数。

mov ax, 0f000h
mov ds, ax
mov bx, 0
mov dx, 0
mov cx, 32
       
s: mov al, [bx]
cmp al, 32
__________
cmp al, 128
__________
inc dx
       
s0: inc bx
loop s

解答

mov ax, 0f000h
mov ds, ax
mov bx, 0
mov dx, 0
mov cx, 32
       
s: mov al, [bx]
cmp al, 32
jna s0
cmp al, 128
jnb s0
inc dx
       
s0: inc bx
loop s
