Your bos is right. It's your opportunity to learn something most if not all programmers do not understand: That "normal" (the majority of) people do not think like programmers. The opportunity and reword can be significant -- way beyond this project. Here are the exact step to take. 1. Using GUI tools (as an example Win API based tools) recreate the DOS program interface, display and functionality to GUI. Provide identical functionaly and interface but convert the infrastructure such as database to your final platform -- as an example a relational database such as MYSQL or MS SQL instead of a DOS based databse system. 2. Get the users and owner to "test" the new system -- do not add features at this stage - but list notes, comments, criticism and requests for new functionality. 3. Implement regression and intrval backup as well as the web infrastructiure for exapnsion. 4. After testing move to parellel usage of both the old and new systems. 5. After testing comleted move the entier operation to the new system. 6. Start your designe process for new features based using what you have leanred. 7. Start adding new features, one by one with incremental regression. Feel free to contact me for tools that were designed to do just that. m@views.com
