汇编语言程序设计实验报告
实验一
实验内容：熟悉DOS编程环境：编写一个DOS环境的汇编语言程序，要求 从键盘输
入一串字符，去除连续重复的字符后再显示，如：输入一串为“aaawwweerrty”的字符串，输出结果应为‘awerty’
实验目的：通过上机实践加深对16位环境下编程的了解
学会使用debuge调试程序
实验代码：
ASSUME CS:CODE, DS:DATA
DATA SEGMENT
BUFFER DB 60, ?, 60 DUP(?) PRINT DB 'TO INPUT: ' CRLF DB 0DH, 0AH, '$' DATA ENDS
CODE SEGMENT
MAIN:
MOV AX, DATA MOV DS, AX
MOV AH, 9 LEA DX, PRINT INT 21H
MOV AH, 0AH
LEA DX, BUFFER INT 21H
MOV AH, 9 LEA DX, CRLF INT 21H
LEA SI, BUFFER + 1
LP1:
INC SI LP2:
MOV AL, [SI] CMP AL, 13 JZ DISP
CMP AL, [SI + 1] JNZ LP1 MOV DI, SI LP3:
INC DI
MOV AL, [DI + 1] MOV [DI], AL CMP AL, 13 JZ LP2 JMP LP3 DISP:
MOV AL, '$' MOV [SI], AL
MOV AH, 9
LEA DX, BUFFER + 2 INT 21H EXIT:
MOV AX, 4C00H INT 21H CODE ENDS END MAIN
实验代码整体思路：定义一个大小为60的缓冲区，用来存储从键盘输入的字
符串；
调用中断调用，将字符串输入到缓冲区当中；
使用取地址符号Lea取得输入字符串的首地址然后后一位与前一位相比，若相同则将其舍弃，否者将其记录在缓冲区中，循环结束之后在其后补上字符“$”即可一次输出，无单个输出

检测所编程序的正确性：
编译所建的1.asm文件：
按下回车键之后开始编译，如下图所示，编译结束表明没有错误不存在警告
