An approach to software maintenance support using a syntactic source code analyser data base : this thesis is presented in a partial fulfillment of the requirements for the degree of Master of Arts in Computer Science at Massey University

In this thesis, the development of a software maintenance tool called a syntactic source code analyser (SSCA) is summarised. An SSCA supports other maintenance tools which interact with source code by creating a data base of source information which has links to a formatted version of program source code. The particular SSCA presented handles programs written in a version of COBOL. Before developing a SSCA system, aspects of software maintenance need to be considered. Hence, the scope, definitions and problems of maintenance activities are briefly reviewed and maintenance support through environments, software metrics, and specific tools and techniques examined. A complete maintenance support environment for an application is found to overlap considerably with the application documentation system and shares some tools with development environments. Program source code is also identified as the fundamental documentation of an application and interaction with this source code is a requirement of many maintenance support tools
