Software maintenance: redocumentation of existing Cobol systems using hypertext technology

Abstract

One of the major problems associated with the maintenance of existing software systems is their lack of documentation. This can make very large, poorly structured programs very difficult to maintain. Nearly all traditional documentation tools are either designed for use in the development stage of the software lifecycle or are report generators such as cross reference generators. The problems of lack of documentation are compounded when applied to third party software maintenance as the staffs are often initially unfamiliar with the code they are maintaining. This thesis describes these problems in detail and evaluates the feasibility of a tool to help with redocumentation based on current hypertext technology.
