一、概述用INTEL 86/300微机系统作为数据采集处理系统时,数据采集处理程序可以用多种语言来编制,ASM-86汇编语言是该机的基本语言,但是编程难度较大;PL/M-86是一种高级语言,而且它可以直接利用微处理机的某些特性,如间接寻址,直接输入/输出等,因此用于编制数据采集程序是十分有效而方便的,但是PL/M-86的输入输出功能较弱,采用交互方式进行采集控制及数据输出都相当繁杂。在这点上,用户感到极为不便。
I. INTRODUCTION When using INTEL 86/300 computer system as data acquisition and processing system, the data acquisition and processing program can be compiled in many languages. ASM-86 assembly language is the basic language of the machine, but the programming is more difficult. PL / M -86 is a high-level language, and it can directly use some of the characteristics of microprocessors, such as indirect addressing, direct input / output, etc., so for the preparation of data acquisition program is very effective and convenient, but the PL / M -86 I / O function is weak, the use of interactive acquisition control and data output are quite complicated. At this point, the user feels extremely inconvenient.
