多任务的分时运行作业环境

Multitasking Time share Operating Environment

该文研究ＤＯＳ系统下一个多任务实时处理系统环境的设计，该系统充分利用８０３８６支持的扩展内存，每个作业以覆盖程序的方式装入扩展内存中运行，并对每个作业（覆盖程序）进行调度管理、对输入输出信息以及覆盖程序常用函数库进行管理。此系统应用于证券实时分析系统中，取得了良好的效果。

The paper discusses multitasking real time operating environment under DOS. It efficiently utilizes extended memory that 80386 supports, so that every task is loaded into the extended memory as overlay program and executed. It also can realize management for overlap program schedule, input output informaton and function library of the overlap program. This system environment can have a good effect when applied in securities exchange real time analysis system.
