MS—FORTRAN77基本绘图子程序

Ms—Fortran77 Fundamental Graphics Subroutines

本文将讨论能被MS—FORTRAN 77所调用的基本绘图子程序的原理与应用。这些子程序是用汇编语言写成,可以在IBM—PC或兼容机上运行。其主要功能是:(1)显示点,(2)画线。这些是计算绘图的基本软件(子程序)。

This paper is intended to cover the principles and applications of the softwares MODE,PLOT and LINE written in Assemble Language,which an be called by MS—FORTRAN77 on IBM Personal Computer or com- patiblesas subroutines.The functions of these subroutines are(1)changing the mode of screen,(2)ploting a point and(3)drawing a line,which are the basic softwares of computer graphics.
