(1)编写顺序结构.asm文件实现y=10x,并能够计算在x=15时的值 (2)编写顺序结构.asm文件实现数据段和附加段两个数据值的交换

dseg segment
  x db 15
  y db 0
dseg ends
cseg segment 'code'
     assume ds:dseg,cs:cseg
begin: mov ax,dseg
       mov ds,ax
       mov al,x
       mov cl,2
       shl al,1
       mov bl,al
       shl al,cl
       add al,bl
       mov y ,al
       mov ah,4ch
       int 21h
cseg ends
     end begin
