实现不同语言的相互调用是程序设计中的一种有效方法,这样做的目的是避开某一种语言的弱点,而利用另一种语言的优点,这将有助于程序设计中的高效、简捷和模块化。本文论述在IBM微机上实现FORTRAN、PASCAL、C等三种高级语言相互调用的机制,并通过实例介绍这三种语言相互调用的接口。 相似文献

在ULTRIX(一种UNIX操作系统)环境下,Pascal,Fortran,Modula-2和C语言之间可以相互调用。这是因为这四种语言对过程或函数的调用在机器指令级的调用方式是一致的,而且它们都可以分离编译。 要实现这四种语言之间的相互调用,关键是要解决它们之间的接口技术问题。对此,我们进行了必要的开发和摸索,并且在VAX-11/785计算机上实现了这种技术。 相似文献

为了解决软交换系统提供的电信业务之间的依赖、冲突和相互调用的交互关系,提出了一种处理算法,通过创建3个函数矩阵:依赖关系处理函数矩阵、冲突关系处理函数矩阵、业务间相互调用关系处理函数矩阵,在接收到上报的业务触发消息时进行业务间的依赖和冲突关系的检测处理,在当前业务逻辑实例执行完毕时进行业务间相互调用关系的检测处理。该算法简单、高效、通用性强,提高了开发效率。 相似文献

MATLAB具有强大的数据处理能力和建模仿真功能,并提供了大量友好的接口,但是并未绑定HLA,无法直接参与HLA仿真。在MATLAB与java相互调用和prti1516的java API基础上,综合比较现存的MATLAB用于HLA仿真的各种方法的优劣,以及MATLAB与java相互调用方法的优劣,设计了MATLAB-HLA Toolbox,并详细介绍了工具包实现过程中的关键技术。通过工具包,可以方便的实现在MATLAB环境中开发HLA联邦成员,从而实现MATLAB用于HLA仿真,实现MATLAB和HLA优势的结合。工具包的研究开发对于其他仿真软件用于HLA仿真具有一定的参考价值。 相似文献

用异种程序设计语言编写的程序模块,要实现相互调用,必须解决不同语言环境之间转换的接口。在一些配置了UNIX操作系统的小型、微型计算机上,仅提供了FORTRAN,PASCAL程序调用C子程序的接口手段。本文探讨并实现C程序调用FORTRAN子程序模块的接口方法,最终实现C,FORTRAN,PASCAL程序模块之间的交叉调用。 相似文献

A graph-theoretic method for integration of process and control system (IPCS) syntheses with different controllability notions has been proposed in the present paper. The foundation of this integration is a well-established, graph-theoretic approach to process synthesis in conjunction with the analysis of structural controllability based on digraph-type process models. Unambiguous structural representation of the resultant integrated process and control systems, IPXS structures in brief, has been introduced for unambiguous representation of a process structure, it is rendered possible as an extension of the directed bipartite graph, the P-graph. Different set of axioms are proposed for describing the case of disturbance-rejective regulable and the combinatorially feasible and controllable structures in the special cases considered: the case of structural controllability and the case of fault-tolerant controllability. These axioms make the synthesis computationally more effective by considering very simple engineering knowledge. The maximal controllable structure of an IPXS synthesis problem has been defined as the union of combinatorially feasible and controllable IPXS structures. Thus, the mathematical programming model, e.g. MINLP model, of an IPXS synthesis problem can be and should be derived from the maximal controllable structure. Different versions of a fundamental polynomial time, combinatorial algorithm are presented for identifying the maximal controllable structure. The resultant IPXS structures are compared with the structures synthesized without considering their control systems. 相似文献

Analysis of the work of the chemical process designer has revealed that his activity - in essence, repeated synthesis such as analysis problem-solving - has its own structure so it may be regarded as a system. An attempt has been made to construct a modular computer programming system to support the process designer's work. The programming system's modules reflect nodal designing activity such as balancing, simulation, economic evaluation and optimization, and the necessary transfer of information from one design step to another is secured by integral communication between the modules. Particular attention has been paid to the development of a designer-machine interface to enable an easy dialogue with the programming system. Features of the Design Integrated System are shown by applying DIS to a simple but typical chemical process. 相似文献
