1、还有就是如何通过时钟中断调用来确定表的时针、分针和秒针的位置。设计中遇到的问题和解决的步骤、方法：遇到问题： 在课程设计中遇到的最大的困难是如何产生中断，对中断向量表的装载还比较模糊，对中断的初始化、具体设置、中断的返回还不是很清楚，最主要如何是通过时钟中断调用来确定表的时针、分针、和秒针的位置，并通过条用相关子程序画在屏幕上开始是不是很明白。解决步骤、方法： 在此过程中我认真翻阅了课本，重点对课本中断这一章做了详细的研究和学习，同时还借阅了王爽的汇编语言一书，特别是对其中的一些常用的中断进行了全面的学习和深入的研究，基本上弄懂了各个中断的作用和应用，通过对这些中断的学习，使我对中断有了更深一

2、步的认识，因而在相关程序的设计方面就容易了很多。设计结果：程序设计完成后，通过编译器编译成可执行文件.exe后，双击即可运行此指针显示的程序，同时屏幕上会出现一个时钟表盘，表盘上会显示相应的系统时间，同时在程序运行过程中，按C键可改变钟表界面各个部分的颜色；按B键可扩大表盘；按S键可听简单的音乐；按Q建退出程序。 附录1：程序运行截图（2张）附录2：源程序列表extrn music:far,gensound:far;* 堆栈段 .286;STACK_SEG SEGMENT STACK STACK_BUF DW 120 DUP（?） TOP EQU $-STACK_BUFSTACK_SEG EN
