求一个嵌套循环的代码例子

[智能卡_Snooper]

data segment 
msg db 'hello, world', 0dh, 0ah, '$'
data ends

stack segment stack para 'stack' stack
	sta   db  256 dup(?)
stack ends

code segment
assume  cs:code,ds:data,ss:stack
start:
	mov ax, data
	mov ds, ax
	
	mov dx, offset msg
	mov ah, 9
	
	mov cx, 3
loop1:
	push cx
	mov cx, 4
loop2:
	int 21h
	loop loop2
	pop cx
	loop loop1
	
	mov ah, 4ch
	int 21h
code ends
 end start

循环 3 * 4次的小例子。

data segment 
msg db 'hello, world', 0ah, 0dh, '$'
msg2 db 'hello, world', '$'
d db 1h
data ends

stack segment stack para 'stack' stack
    sta   db  256 dup(?)
stack ends

code segment
assume  cs:code,ds:data,ss:stack
start:
    mov ax, data
    mov ds, ax
    
    ;mov dx, offset msg
    ;lea dx, msg
    mov ah, 9
    
    mov cx, 3
loop1:
    push cx
    mov cx, 4
loop2:
    cmp d , 0CH
    jne p2
p1: 
    lea dx, msg2
    jmp p3
p2: 
    lea dx, msg
p3: 
    int 21h
    inc d
    loop loop2
    pop cx
    loop loop1
    
    mov ah, 4ch
    int 21h
code ends
 end start

帮忙简化一下

[code=Assembly];键盘输入10个数（都是无符号数，字类型），要从大到小求排序，然后屏幕输出
data segment
number dw 10 dup ( 0 ) ;输入的数据
inputmsg db 'please input :', 0ah, 0dh, '$'
data ends
stack segment stack para 'stack' stack
sta db 256 dup(?)
stack ends
code segment
assume cs:code,ds:data,ss:stack
start:
mov ax, data
mov ds, ax

;输入
mov cx, 10 ;输入10个数
mov si, offset number

begin:
call printstr
call inputval
inc si
inc si
loop begin

;排序开始，用冒泡排序
mov cx,9*2
mov si,offset number

xor bx,bx ;楼上的这里错了
Inner:
mov ax,[bx+si]
cmp ax,[bx+si+02h]

push [bx+si+02h]
mov [bx+si+02h],ax
pop [bx+si]

inc bx
inc bx
cmp bx,cx

dec cx
dec cx

;排序结束
