实验9 根据材料编程

1.补全程序t1.asm，完成在屏幕上输出内存单元中的十进制二位数。

assume cs:code,ds:data
data segment
     db 12
     db ?,?
data ends

code segment

start:  mov ax,data
          mov ds,ax

          mov ah,0
          mov al,ds:[0]
          mov bl,10
          div bl
          mov ds:[1],al
          mov ds:[2],ah

          mov ah,2
          mov dl,ds:[1]
          add dl,30h
          int 21h

          mov ah,2
          mov dl,ds:[2]
          add dl,30h
          int 21h

          mov ax,4c00h
          int 21h

code ends
end start

2.补全程序t2.asm，完成在屏幕上输出data段定义的5个十进制两位数，数据和数据 之间以空格间隔。

assume cs:code,ds:data

data segment
    db 12,35,96,55,67
data ends

code segment
start:  mov ax,data
        mov ds,ax
        mov bx,0
        mov cx,5

      s:  mov ah,0
          mov al,ds:[bx]
          mov dl,10
          div dl
          mov ds:[5],al
          mov ds:[6],ah
 
          mov ah,2
          mov dl,ds:[5]
          add dl,30h
          int 21h

          mov ah,2
          mov dl,ds:[6]
          add dl,30h
          int 21h

          mov ah,2
          mov dl,' '
          int 21h

          inc bx
          loop s

          mov ax,4c00h
          int 21h

          code ends
          end start

 3.

assume ds:data, cs:code，ss:stack
data segment
       db 'welcome to masm!'  
       db 2H,24H,71H         
data ends

code segment
start:  mov ax,data
          mov ds,ax            
        
          mov ax,0b800H
          mov es,ax 

          mov cx,3
          mov al,0
          mov si,0
          mov di,0
          mov bx,0

   s0:  mov bl,0
          push cx
          mov cx,10h

     s:  mov al,ds:[bx]
          mov es:[si+0720h],al
          inc si
          mov al,ds:[di+10h]
          mov es:[si+0720h],al
          inc si
          inc bx
          loop s

          inc di
          pop cx
          add si,80h
          loop s0

          mov ax,4c00h
          int 21h
code ends

end start
