一、概述当今的世界计算机的使用日趋普及,而微型计算机以它独有的特点,得到各类人员的广泛使用。绘图仪作为微计算机的一个外部设备,如能更好的发挥其作用,将给我们的工作带来极大的方便。本软件正是以这一目的而编写的,它由一组十二个用 FORTRAN 语言编的子程序组成。这些子程序能够产生特定的操作命令,并发送给 SR—6602绘图仪,进行基本的绘图操作。其具有画函数关系曲线,画坐标轴,写字符、数字,画圆、弧线、对数曲线图等功能。子程序可直接由用户的 FORTRAN 程序调用。在 IBM-PC/XT 微计算机上进行了实际运用,绘图仪通过并行口和计算机相连。
First, an overview The use of computers in the world today is increasingly popular, and the microcomputer with its unique features, has been widely used by all types of personnel. Plotter as an external micro-computer equipment, if we can play a better role, will bring great convenience to our work. This software was written for this purpose and consists of a group of twelve subroutines compiled in the FORTRAN language. These routines can generate specific operation commands and send them to the SR-6602 plotter for basic drawing operations. It has draw function curve, draw axis, write characters, numbers, draw circles, arcs, logarithmic curves and other functions. Subprograms can be called directly from the user’s FORTRAN program. The practical use was made on the IBM-PC / XT microcomputer, which was connected to the computer through the parallel port.
