    Cobol program analyser and workbench - phase 1 : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Computer Science at Massey University
    (Massey University, 1985) Tan, Kay Meng
    This dissertation addresses a number of important software maintenance problems which fall within the framework of software management and software engineering. Compiling techniques were used to present in a standard form the structure of the COBOL program PROCEDURE DIVISION; as well as providing a framework for some complexity measures of a given COBOL program. The latter can give some measure of the ease of software modification during the software maintenance phase. The purpose of the project of which this thesis is a part is to build up a database which will completely specify a COBOL program and enable it to be analysed in various ways related to maintenance, enhancement and other tasks. A COBOL program information system ( M.JCAS) has been designed for use by the applications programmer, to acquire the information about a COBOL program ( e.g. complexity measures, control flow analysis ) by analysing the structure of the COBOL program. Various software methods such as structured programming, structured design, top-down design and bottom-up program testing were used throughout the MJCAS system development process. The finite-state machine concept was used to construct a COBOL lexical scanner. The COBOL programming syntax was parsed by the top-down recursive-descent method. The COBOL program was reformatted according to a coding standard to show the structure of the COBOL program. Many complexity measures are mentioned in this thesis. A combination complexity measure method and guidelines are suggested. A COBOL program complexity factor is proposed. In general, the program complexity measure could apply to other programming languages.

    COBOL language implementation via English : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Computer Science at Massey University
    (Massey University, 1976) Kessell, Owen D
    In this thesis, synthesis of COBOL programs is discussed. The programs are generated with the aid of an interactive Natural Language dialogue. Reasons for and against the use of English as a general programming aid are discussed, also the use of English in program synthesis is discussed. The major portion of this thesis describes the design of the system known as CLIVE. The discussion illustrates the relative ease in which COBOL programs can be generated by using ordinary English responses.
