汇编程序在屏幕上显示一个字符串“Hello”

datasegment

stringdb'Hello',13,10,'$'；字符串以’$’符号结尾，以单引号括起来

dataends

codesegment

assumecs:code,ds:data

start:；程序的入口地址

pushds；saveolddatasegment

subax,ax；ax寄存器清零，作为数据段0偏移地址

pushax；零偏移地址入栈

movax,data

movds,ax；把数据段地址装入数据段寄存器ds

leadx,string；把字符串首地址装入dx寄存器，或写成movdx,offsetstring

movah,9；DOS功能调用，在屏幕上显示字符串

int21h；DOS中断

movah,4ch；returntoDOS

int21h

codeends

endstart；汇编的结束，程序在此执行

Answer 2

DATAS SEGMENT
BUF DB 'Hello,Assembly language.$'
DATAS ENDS
CODES SEGMENT
ASSUME CS:CODES,DS:DATAS
START:
MOV AX,DATAS
MOV DS,AX
MOV DX,OFFSET BUF
MOV AH,09H
INT 21H

MOV AH,4CH
INT 21H
CODES ENDS
END START

Answer 3

data segment
msg db "Hello，Assembly language",0dh,0ah,'$'
data ends
code segment
assume cS:code,ds:data
start: mov ax,data
mov ds,ax
mov dx,offset msg
mov ah,9
int 21h
mov ax,4c00h
int 21h
code ends
end start
