【第五章】实验4

向内存0:200~0:23F一次传送数据0~63(3FH)

assume cs:codeseg

codeseg segment
	mov ax,0020h
	mov ds,ax
	mov bx,0000

	mov cx,64 ；循环64次
s:	mov ds:[bx],bx ;将bx中的内容（0~63）移动到0020:0000~0020:003F中
	inc bx	
	loop s

	mov ax,4c00h
	int 21h
codeseg ends
end

将下列程序“mov ax,4c00h”之前的质量你个复制到内存0:200处

assume cs:codeseg

codeseg segment
	mov ax,codeseg
	mov ds,ax
	mov ax, 0020h
	mov es,ax
	mov bx,0

	mov cx,18
s:	
	mov al,[bx]
	mov es:[bx],al
	inc bx		
	loop s

	mov ax,4c00h
	int 21h
codeseg ends
end
