COBOL is now more than 20 years old and will probably survive to become much older. Since it has some features which are out of date it is desirable to adapt at least the program style to some standards of modern programming languages. The adaption is not only a matter of style but also of costs of program production and program maintenance. This paper presents constructional rules for programming in COBOL which by-pass some of the drawbacks and allow more readable and more maintainable program structures. Finally a postprocessor is presented, that allows verification of the chosen constructional rules and documentation of the resulting programs.  相似文献

SURGE, a COBOL pre-processor for the machine generation of source programs, is described. The article presents the coding procedure by which the user communicates with SURGE, and briefly introduces the general logic of both the pre-processor and generated programs. The main capabilities of SURGE are described as file sorting, selective retrieval and tabular report preparation, including multiple levels of totals and a capability for certain other kinds of computation. Non-proprietary and relatively machine-independent, this package appears to reduce the need for hand-crafted COBOL programs and to be remarkably easy to learn and use. It is suggested that SURGE also may offer a suitable prototype for extending the concept of source-program generation to other goals such as file updating and the production of FORTRAN programs.  相似文献

A COBOL preprocessor to implement Michael Jackson's program design language, Schematic Logic, has been written and used in the Computation Department at UMIST. This paper investigates the problems inherent in using preprocessors of this type and details the advantages which accrue from the preprocessor when teaching and using the Jackson Method.  相似文献

After a brief review of the use of flowcharts both before and after the completion of a program, this article illustrates and compares the graphic output of four automatic flowcharting packages for COBOL programs. These packages are Autoflow, Dynachart, Quickdraw, and Axiom One. Primary consideration is given to the effectiveness of various notational conventions and schemes for geometric representation. The specimens presented may also suggest preferred practices for adoption in preparing hand-constructed documentation.  相似文献

随着IT技术的发展,电算化会计信息系统进一步向深层次延伸,无疑给企业带来了巨大的效益,但也同时给会计电算化带来了新的问题和挑战。目前,不少会计软件开发公司为了方便财会人员纠正会计电算化核算中的差错,纷纷在会计核算软件中增设了“反记账、反结账”功能,这项功能的使用确实给财会工作带来了诸多方便,但也产生了一些负面效应。本文就会计电算化中“反记账、反结账”发表点观点。  相似文献

We propose an approach to the construction of grammars for existing languages. The main characteristic of the approach is that the grammars are not constructed from scratch but they are rather recovered by extracting them from language references, compilers and other artifacts. We provide a structured process to recover grammars including the adaptation of raw extracted grammars and the derivation of parsers. The process is applicable to possibly all existing languages for which business critical applications exist. We illustrate the approach with a non‐trivial case study. Using our process and some basic tools, we constructed in a few weeks a complete and correct VS COBOL II grammar specification for IBM mainframes. In addition, we constructed a parser for VS COBOL II, and were the first to publish a (Web‐enabled) grammar specification so that others can use this result to construct their own grammar‐based tools for VS COBOL II or derivatives.

Most syntax analysis phases of COBOL compilers are written as sequences of procedural code instructions each of which validates a particular part of the syntax of a COBOL program. This paper examines the structure of a syntax driven COBOL compiler and a practical implementation is described. The problems encountered with this type of compiler construction are explained, and its advantages are examined. Finally, some other potential applications of syntax driven technology are suggested.  相似文献
