21、出程序的编写方法。2) 熟悉系统功能调用的方法。3) 熟悉动画程序的编写方法。二、实验内容1在 CRT 上每隔一秒连续显示字符 09。编程提示为了使输出的字符之间有空格，在每一个循环中输出一个 09 的字符和一个空格。为了输出 09，置存放器 BL 初值为 0，每循环一次使其增量。为了保证输出是十进制，增量后用DAA调整指令。由于输出为一位十进制数，用AND0FH指令屏蔽高 4 位。2用系统功能调用将‘HELLO由键盘输入，再从屏幕输出‘_HELLO_。3编制在屏幕上画线的子程序，调用该子程序画一矩形。4编制字母下落一行的子程序，调用该子程序使字母从屏幕顶部下落到底部。

22、5创立一磁盘文件，保存从键盘输入的字符串。6编写程序用设置系统时间，首先从键盘以十进制数形式输入时间，然后修改系统时间，并重新以十进制形式显示时间。7编写程序将屏幕分割成格状，每一格涂上不同颜色，格数从键盘输入。8编写程序在屏幕上显示菜单，输入相应菜单的序号后，选种该菜单项。三、实验设备PC 机一台四、实验步骤1) 按程序流程图编制实验程序。2) 输入程序。3) 汇编、连接程序，执行程序，检查结果。4) 程序的执行可用 DEBUG 的 G 命令,也可用 T 命令单步跟踪执行。五、 程序 实验五E_AM51STACKSEGMENTSTACKDB1024DUP0STACKENDS CODESEGM
