实现一次用内存0:0-0:15单元中的内容改写程序中的数据,完成程序:
assume cs:code code segment dw 0123h,0456h,0789h,0abch,0defh,0fedh,0cbah,0987h start: mov ax,0 mov ds,ax mov bx,0 mov cx,8 s: mov ax,[bx] mov cs:[bx],ax add bx,2 loop s mov ax,4c00H int 21H code ends end start
assume cs:code code segment dw 0123h,0456h,0789h,0abch,0defh,0fedh,0cbah,0987h start: mov ax,0 mov ds,ax mov bx,0 mov cx,8 s: mov ax,[bx] mov cs:[bx],ax add bx,2 loop s mov ax,4c00H int 21H code ends end start
