The seismic kernel system — a large-scale exercise in fortran 77 portability

The portability of software has become a major commercial issue in recent times. Such portability does not come easily, as few if any computer languages are really portable in practice. An additional complicating factor, especially in the commercial environment, is that the resulting software must be efficient. This paper describes the design and successful implementation of a 500,000+ line portable FORTRAN 77 package for the processing of seismic data. The package exhibits demonstrably high efficiency on a wide variety of machines from minicomputers to the largest supercomputers. Experiences gained during this exercise throw much light on the integration of the various thought processes which occur during the software engineering cycle, especially the notion of locality.     

FORTRAN语言开发软件时的汉字显示

本文利用ＦＯＲＴＲＡＮ图形库函数，通过对１６点阵和２４点阵汉字库的访问，获取汉字字模后，建立用户小汉字库，从而实现在应用程序设计中文字和图形的同时显示界面，大大改善了ＦＯＲＴＲＡＮ程序的输出效果和速度，并且大大节约了内存占用量，使应用程序摆脱了对中文ＤＯＳ环境的依赖，在ＭＳＤＯＳ下可以直接实现汉字字符的各种显示，使得ＦＯＲＴＲＡＮ语言更加实用、方便，为中文应用程序的开发提供了一种简捷的途径。     

分布式GASOR系统设计中FORTRAN与C#混合语言编程研究

C#语言是一个先进的、安全的、面向对象的编程语言。以前的开发者为编写了许多已经历时间的考验。成熟、稳定的FORTRAN计算程序。FORTRAN语言本身并不适合用来开发窗口界面程序和互联网应用程序。因此为了提高程序的使用效率提高代码的重用率有必要对原FORTRAN程序进行改进使得原有性能优良的FORTRAN代码可以被在C#下调用,最大限度的发挥两种语言各自的优点。本文着重研究了这两种语言混合编程的方法,及其实现。

Debugging methods in recursive structured FORTRAN

A version of structured FORTRAN named STAR is introduced. STAR allows recursive subroutines. Implementation problems such as parameter passing by value and local variable stacking are discussed. The major difficulty in the preprocessor approach is debugging. We claim that execution profiles are strong debugging aids, and demonstrate how to debug a STAR program at source language level with the clue in the profiles plus assertion statements. We make use of a quicksort program as an example.     

SOLVUS: A FORTRAN IV program to calculate solvi for binary isostructural crystalline solutions

SOLVUS is a FORTRAN IV program which utilizes experimental data to calculate a complete miscibility gap between two isostructural phases. This binodal curve and the corresponding spinodal curve are plotted on temperature-composition axes. A formulation of the excess Gibbs energy of mixing is required for the calculation. Three different formulations are used, that is the Margules, van Laar, and Scatchard-Hamer types, in alternate solvus calculations. The temperature dependences of parameters in the three formulations are fitted by least-squares regression to a hyperbolic tangent, given sufficient data, or else to a line. Sample calculations are presented for six systems, high albite-sanidine, halite-sylvite, calcite-siderite, pyrite-vaesite, oldhamite-niningerite, and oldhamite-alabandite.
