Cobol Remote Integrated Development Environment Research And Implementation

COBOL is abbreviation of Common Business-Oriented Language, it is a kind of orientcd-business programming language which is an old language produced in the late 196()'s. As high-quality solutions for enterprises, COBOL accounts for the vast majority of commercial software. Nowadays, the majority software which is developed with COBOL operated in UNIX platform, but the disadvantage that the UNIX platform lacks convenient COBOL development tools bring much difficulty on development and maintenance of software. Hence, providing the COBOL programmer a convenient efficient based-UNIX remote COBOL integrated development environment (IDE) has more important research meaning and business value.The author has participated in designing and development of an international cooperating project- COBOL remote IDH. The system adopts the C/S architecture. The Client End, which is on the Windows OS, has a graphic interface and communicates with the Server End. and the Server End, which is on the HP-UX, provides some kernel function modules, such as compiler, debugger, file management and authentication, and so on. In the term, the author mainly engaged in designing and developing of IDE server. On the basis of one-year- practice, the author has had a deep understanding and recognizing on the architecture of IDE server and studied deeply its realizing technology. The main work and contribution on this thesis be summarized as follows:1. Analyze the system architecture of the COBOL remote IDE, and design the Server End modules according to the top-to-bottom rule.2. Study deeply PAM authentication principle and architecture, and complete this system certification function on this foundation.3. Study the file management module, and design the interlace in the Source File Library (SFL) and the flow of file operation with the conceptions of FCT and SFL.4. Analyze the implemented mechanism of project manager on server, put forward a realized method to make use of program to produce Makefile, design and implement tool-mkcblmk-to create automatically Makefile.
