汇编-SEG获取标号的段地址

 

;目的；将welcome to masm复制到段地址0B800h

assume cs:code,ds:data

data segment;数据段
db 'welcome to masm'
data ends 
  
 code segment 
 start:
        mov ax, 0B800h
        mov ds, ax
        
        mov ax, SEG data
        mov es,ax
        
        mov cx,15
        
        mov bx, 0
      s:mov al,es:[bx]    
        mov ds:[bx],al
        inc bx
        loop s
        
        mov ax,4c00h
        int 21h
        
      
 code ends 
 end start

 

注意：mov es,seg data     是错误的
