摘　　要：异种语言编写的程序相互调用，是程序设计者为利用已有软件资源而经常涉及的实用技巧。本文基于Ｃ应用程序调用ＶＡＸ／ＲＧＬ图形库绘图的实践，探讨ＶＡＸ／ＶＭＳ环境中Ｃ语言与ＦＯＲＴＲＡＮ语言的接口方法，其关键在于弥补两者采用的ＶＡＸ过程调用参数传递机构上的差异。然后介绍笔者利用该方法为ＲＧＬ实现的一个Ｃ程序接口软件。Routine calling between codes written in different languages is a useful skill, which allows programmer make better use of existing software resources.This paper investigates an interfacing method between C and Fortran in VAX/VMS environment. The disscussion is based on the author's experience on calling VAX/RGL from the C applications. The key is to flat the gap between the VAX routine parameter passing mechanism in these two languages. Also introduced is a C interface software for RGL, which is implemented by the author according to this method.
