过程控制计算机系统打印输出程序虽然简单,但目前国内还没有通用化。本文从软件包设计角度探讨了输出打印模块通用化设计的准则及其解决的方法,使其构成一个既方便于用户功能进程的设计,又能合理使用系统资源的共享模块。 Process control computer system printout program is simple, but at present there is no universal. In this paper, we discuss the rules of universal design of output print module and its solution from the perspective of software package design, and make it a shared module which is easy to design for process of user functions and can use system resources reasonably.
