2、序，若为其它字符则不显示，继续等待新的字符输入。3. 实验准备(1) 编写实验内容要求的两个程序。(2) 写出调试以上程序，即修改程序的参数，检查结果的操作方法。(3) 熟悉源程序汇编、连接命令的使用方法及要回答的内容。4. 实验步骤(1) 用EDIT或其它编辑软件，编写.ASM源程序，例如HEXASC.ASM及DSPKEY.ASM。(2) 对其进行汇编及连接，产生.EXE文件。(3) 对.EXE文件进行调试运行。 用DEBUG调试运行，学会修改AL内容的方法。 对DSPKEY.EXE侵入不同的字符，分别进行调试。5. 实验报告要求(1) 画出两个程序的流程图，若要独立编写程序，应开出相应的程

3、序清单。(2) 说明本实验是如何利用DEBUG进行调试的。6. 参考程序清单(1)显示AL中两位十六进制数程序：;DISPHEX.ASMCODESEGMENTASSUMECS:CODESTART:MOVAL,3EHMOVDL,ALMOVCL,4SHRDL,CLCMPDL,9JBENEXT1ADDDL,7NEXT1:ADDDL,30HMOVAH,2PUSHAX;原程序无此行INT21H;显示高位ASCII码POPAX;原程序无此行MOVDL,ALANDDL,0FHCMPDL,9JBENEXT2ADDDL,7NEXT2:ADDDL,30HMOVAH,2INT21H;显示低位ASCII码MOVAH,
