Bringing Objects into COBOL: MOORE - A tool for migration from COBOL85 to object-oriented COBOL

Object-orientation and reuse are two techniques, which, combined, can solve many problems in the maintenance of old software. MOORE combines these techniques as a reengineering tool, which helps the user to transform old programs from COBOL85 to object-oriented COBOL. A class library is created to be used for transforming further programs and writing new objectoriented programs. The user should be familiar with the application field and the programs to be transformed. 1 Introduction A decision to renovate software which has been in use for many years must be made primarily on economic grounds. There is extensive literature about renovating old software [Big88], [Big89], [Boo91], [Sig92]. Even the combination of reengineering and object-oriented programming is nothing new; see ESPRIT II projects REDO [Bre91] and REBOOT [Sem93] and the project Software Factory of the EC. Renovation includes many preparatory phases, including inspection, analysis and restructuring of source programs, ide..
