What is Phase Change?

Our sophisticated AI reasoning engine navigates and analyzes the intricate details present in the extensive code that makes up your applications. This empowers developers to swiftly pinpoint the precise code they require. To effectively manage, adjust, or integrate the COBOL applications that are vital to your organization, it is crucial to comprehend every business process, data element, and decision-making component woven into your code. Colleague transforms your code into an indispensable knowledge repository through our logic-driven reasoning engine. Unlike generative AI, our solution offers both precision and clarity. Furthermore, you can explore and compare multiple scenarios by modifying parameters in real-time, ensuring the process remains manageable. This feature enhances your understanding of the potential consequences of modifications, promoting well-informed decision-making. As a result, you can confidently navigate complex coding environments while minimizing risks associated with changes.

What is IBM Developer for z/OS?

IBM Developer for z/OS Enterprise Edition is a modern enterprise development platform designed to help organizations accelerate application development, modernization, and DevOps adoption on IBM z/OS systems. The solution combines Eclipse-based tools, Visual Studio Code integration, browser-based development environments, and advanced debugging capabilities into a unified toolset for enterprise mainframe development. It supports a wide range of programming languages and technologies including COBOL, PL/I, High Level Assembler, REXX, Java, JCL, C/C++, and other z/OS development frameworks. The platform is built to help organizations modernize traditional mainframe workflows while integrating industry-standard DevOps practices such as Git-based source control, CI/CD pipelines, automated builds, and cloud-enabled collaboration. Developers can work within familiar interfaces like Eclipse, VS Code, or browser-based environments depending on their workflow preferences and team requirements. IBM Developer for z/OS Enterprise Edition includes advanced debugging capabilities that support full-context debugging across Eclipse, VS Code, and 3270 environments, giving developers flexible troubleshooting options for complex enterprise applications. The platform also features intelligent development tools such as smart code navigation, syntax validation, control flow diagrams, data flow analysis, and ISPF-style interfaces to improve productivity and code understanding. Security and quality assurance are strengthened through integrated tools like ZCodeScan, which identifies vulnerabilities and performs code reviews across z/OS applications. Code coverage analysis tools help teams measure application testing completeness and understand runtime behavior across executable code paths.
