Research And Implementation. COBOL2002 Cross-platform Integrated Development Environment

The Common Basic Oriented Language (COBOL) was created in 60s of the 20th century. With the development of computer technology, COBOL has made constant evolution in recent years. In 2002, COBOL2002 was established as the latest standard. Nowadays, as high-quality solutions for enterprises, COBOL accounts for the vast majority of commercial softwares. Therefore, the development of a convenient Integrated Development Environment (IDE) for COBOL language has both great academic significance and enormous commercial value.Since 2002, the author has devoted himself to the development of the COBOL2002 system, which is an IDE for the COBOL language. The system adopts the C/S architecture. The client-end, which is on the Windows OS, has a graphic interface and communicate with the Server End, and the server-end, which is on the HP_Unix, provides main function modules: compiler, debugger, file management and authentication. As one of the important participants, the author not only designed the framework of the server-end and communication protocol, but made further investigation on interprocess of communications and put forward the accomplishment means of file management and debugger. All those work constitutes the main part of this thesis.In this thesis, the whole architecture of the COBOL2002 system is briefly introduced first. Then, the design of the framework of the server-end and the design of communication protocol are presented, and thus describe how to communicate with the client-end and provide service for it. After depicting the design and accomplishment of file management and debugger in detail, the conceptions of the File Control Table (FCT) and the Source File Library (SFL) are proposed. Finally, the deficiency of the system and some future work are discussed.
