1、优质参考文档中国石油大学华东现代远程教育实验报告课程名称：微机原理及应用 实验名称：循环程序设计 实验形式：在线模拟+现场实践 提交形式：在线提交实验报告学生姓名：褚东 学号:1796414800002年级专业层次：17电气自动化技术 高起专 学习中心：山东枣庄函授站新提交时间：2021年7月10 日一、实验目的1 掌握单重循环及多重循环的程序设计方法；2 学会针对不同的问题，选用不同的组织循环的方法；3进一步熟悉利用DEBU程序、CODEVIEW试程序的方法，并检查和验证结果的正确性。二、实验内容1. 字数组定义如下：ARRARDW12,78,55,4,125,96MARDW?编制程序求出该

2、ARRA数组中的最大数放入MAR单元。datasegme ntarraR dw 12,78,55,4,125,96maRdw ?data endscodesegme ntassume cs:code,ds:datastart:movaR,datamovds,aRmovsi,0movaR,arraRsimovcR,5aga in:add si,2dec cRjcRz eRitcmpaR,arraRsija aga inmovaR,arraRsijmp aga ineRit:movmaR,aRmovah,02hint 21hmovah,4chint 21hcode endsend start2.

3、预留字符串口令,输入口令串与预留密码串比拟。假设匹配那么显示“MATCHCONGRATULAT,N否那么显示“ NOMATCH!,并让用户重新输入，程序能对口令进 行测试，但测试次数最多3次，假设3次输入密码皆错，给出相应的提示信息，程 序退出。datasegme ntpassworddb 123456in putdb20,?,20dupcountequ 6str1db0dh,0ah,match!c on gratulatio n$str2db0dh,0ah, no match!pleasei nputagai n:$str3db0dh,0ah,pleasei ntoutRoupassword
