A shorthand preprocessor for IDMS COBOL

Aspects of software development using Codasyl COBOL DML are considered. In limited trials, a preprocessor which makes a terse DML syntax available has been found to increase programmer productivity and improve software quality.     

Input/output in high level programming languages

A system's input/output is its communication with the other systems in its environment. By viewing the relationship as communication between partners, we identify the fundamental requirements in input/output programming, and discuss the responses of various programming languages to these requirements. Traditional programming languages provide either nothing or an expensive incomplete solution. The new languages Modula and Ada now offer major improvements in this area. We describe the style of their solutions, and give corresponding guidance for low-level input/output programming.     

An experimental COBOL restructuring system

Although COBOL lacks many features required to support structured programming, it can be used to simulate reasonably well-structured programs. This simulation is particularly important for restructuring of poorly structured old programs. This paper describes the formulation of and experiments with a practical methodology for conversion of unstructured COBOL programs into reasonably well-structured equivalents. The discussion includes the overview of an automatic COBOL restructuring system, the results of an experiment with this system and an interpretation of these results.     

New techniques for COBOL programmers

Structured programming has become one of the most widely discussed topics among DP professionals. Despite this, however, COBOL programmers, responsible for the majority of ‘bread and butter jobs’, have been left mostly on their own. The article attempts to review the history of programming and list the areas essential for any future improvement and advancement of the programming profession, inclusive of systems analysis, education and training, and programming methodology. An alternative approach to structured programming in COBOL using decision tables is outlined and confronted with the concept of the so-called functional programming.     

CICS在银行联机事务处理中的研究

随着中国加入WTO,中国的银行面临的竞争越来越激烈。大型机技术与其它系统相比,在大规模数据处理上占有绝对优势。随着银行业务的扩大,银行联机事务量迅猛增加,业务与业务之间具有更加复杂的关系。CICS(Customer Information Control System)是IBM用于管理联机事务处理的最主要的处理平台,适用于有大量突发联机事件的系统。该文基于IBM大型机技术,分析归纳CICS的技术特点,对银行联机事务处理进行探讨。     

浅谈基于主机的COBOL教学实验

在主机上学习COBOL语言就是为了应用开发,COBOL语法教学本身不难,难点在于如何消除学生对主机平台的陌生感,接受COBOL语言的编程风格和体会COBOL在商业应用开发方面的优势。本文分析了基于主机的COBOL教学实验的目标,并给出了相应的实验大纲以供参考。     

COBOL到Java源代码翻译中的数据类型转换*

提出了一种功能等价的类型封装和嵌套方法,可以有效地将COBOL数据描述映射到Java类型系统.该方法已在所开发的COBOL2Java翻译系统中进行应用,通过了近400万行的真实银行商用系统的测试.实验结果表明,此方法正确有效,并且提高了生成代码的执行效率和可读性.     

Current data-management systems: Problems of application in economic geology

The application of data-management systems in economic geology is becoming increasingly user oriented and machine independent. Many mineral-deposit computer systems remain data dependent or fixed formatted but an efficient data system with a proper data-manipulation language needs specific data structures, free format, and a prospective package of generalized modules for the user. Data management primarily requires clear formulation by geoscientist in cooperation with system analyst to serve many activities including problem solving, data content, and decision-making.File-management systems in economic geology involve: file definitions, data validation, data loading, and updating and retrieval. Structuring of a data file seems to be a clue to a successful and long-term file-management system in applied geosciences. Many commercially available file-management systems should be applied in economic geology because the functions which modern computers can perform in assisting file-management development do not essentially differ from those of other data-processing undertakings. The only specific problem in the geosciences is location and graphic form of most geoscience data presented as point, lineal, areal, spatial (three dimensional) input/output information.Data-base management systems provide interconnection between files themselves as well as between different items for different files. Few typical file-management or data-base management systems for geoscience and resources data will be compared in the table form. The paper concludes the problem of choosing and developing an effective data-base management system for its application in economic geology.
