An automated logic design and code writing system that integrates Program Documentation, Design, LogicCoder is a GUI system that introduces a new Software Systems, Design, Coding, Maintenance and Documentation paradigm. It helps you to develop systems where the focus and emphasis is on the intellectual value of the development. It does this by shifting the focus of the end product away from the source code to that of correctness of design, documentation, accuracy and quality of program source code. Source code design, code writing, documentation and maintenance is automated, integrated and presented in a single document interface. There are less chances of committing syntax and semantics errors. LogicCoder can also be used with LogicExtractor to analyse existing source code for correctness and to document the code logic design using structured flowcharts. LogicCoder is fast, reliable and easy to use. Our online tutorial LogicExtractor is a software system that allows you to analyse the control logic of a source program in a selected programming language by displaying this logic in a structured flowchart. LogicExtractor helps you to extract the intellectual value of your source program to an interface system that is independent of the implementation language. This system allows you to develop easily maintainable documentation with the use of flowcharts. You can use LogicCoder to manipulate the control logic so as to create new or modified programs. LogicExtractor enhances the usability, reusability, re-engineerability and maintainability of legacy source code. Use LogicExtractor to generate flowcharts from your source code to get a accurate view of your code logic and to document your code.
