一、前言各类微型和袖珍电子计算机近年来在国内的拥有量增长很快,例如夏普PC—1500机,据不完全统计,已有十多万台开始进入生产、科研和教学的基层单位,遗憾的是这些计算机使用水平很低,以化工部门为例,80%的袖珍机被当作计算器使用。其原因主要是缺乏实用性强而操作简单的程序。编制实用的计算机程序不是一件轻而易举的事,即使熟悉计算机语言,也要耗费大量的精力和时间。 I. INTRODUCTION Various types of miniature and pocket-sized computers have enjoyed rapid growth in domestic usage in recent years. For example, the Sharp PC-1500 machine, according to incomplete statistics, has started to enter the grass-roots units of production, research and teaching. Unfortunately, these computers have low levels of usage. In the chemical industry, for example, 80% of pocket-sized PCs are used as calculators. The main reason is the lack of practical and easy to operate procedures. Compiling practical computer programs is not a trivial matter, consuming a lot of energy and time, even if you are familiar with computer languages.
