about phase change
Phase Change's market-entry product, COBOL Colleague, reads and comprehends COBOL source code like human developers. It creates a unique program representation on which AI reasons, learning every aspect of your applications to acquire complete program knowledge.
Then it communicates its knowledge with an interactive and visual interface to collaborate with developers to solve application problems (such as finding and fixing bugs), shield the organization against application knowledge loss, and improve development productivity.
