输入输出程序设计 一、实验目的 1) 掌握输入输出程序的编写方法。 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，置寄存器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AND 0FH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。5）创建一磁盘文件，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
