如何实现驻留内存整点报时热键激活功能的动态时钟

How to Realize a Risident Program of Dynamic Clock Ringing at Every Hour and Being Activated by A Hot Key

终止并驻留内存(TSR)程序是一种特殊的DOS应用程序,它能快速、方便、及时地处理许多暂驻程序不能处理的事件,使单任务的DOS操作系统能够实现一定程度的多任务处理能力。本文尝试采用TSR编程技术使用汇编语言编写一常驻内存、整点报时、热键激活的动态时钟程序。

: TSR program is a special kind of application programs in DOS environment.They can process many tasks faster and more convenient than some other non -- TSRones do, and without any delay. Therefore the multi -- tasks processing function can berealized in certain degree by a TSR program in the environment of DOS, a single -- taskoperating system. This paper gives a program of dynamic clock ringing at every hour, written in as-sembly language, realized with the TSR method and activated by a hot key.
