eXplain vs. Rocket COBOL Analyzer vs. DoubleCheck Code Analysis

eXplain is a powerful solution crafted by PKS Software GmbH designed for analyzing code and evaluating legacy systems, particularly focused on conducting thorough assessments of legacy applications on mainframe platforms, such as IBM i (AS/400) and IBM Z. This software provides organizations with valuable insights into the software's structure, content, and helps identify which components could be retained, upgraded, or deprecated. By allowing users to import existing source code into a dedicated "eXplain server," the tool removes the need for installations on the host system and employs advanced parsers to analyze several programming languages, including COBOL, PL/I, Assembler, Natural, RPG, and JCL. Additionally, it examines relevant information from databases like Db2, Adabas, and IMS, as well as job schedulers and transaction monitors. eXplain establishes a centralized repository that acts as a knowledge repository, generating cross-language dependency graphs, data-flow diagrams, interface evaluations, groupings of related modules, and detailed reports on resource and object utilization. This functionality enables users to visualize the interrelationships within their code, thereby deepening their comprehension of the software ecosystem. Furthermore, by providing a clearer understanding of their legacy systems, eXplain equips organizations with the tools needed to make strategic decisions about their software's future. Ultimately, the tool enhances operational efficiency and drives informed technological advancements.

Understanding large, complex applications should not rely on guesswork. Rocket® COBOL Analyzer™ is a comprehensive code analysis and visualization solution designed to provide clear visibility into your entire application portfolio. It enables executives, developers, and analysts to quickly understand complex business logic, relationships, and dependencies across the codebase. By transforming intricate code structures into intuitive visual insights, the platform allows IT teams to plan and execute changes with confidence and precision. It offers the ability to visualize application dependencies at scale, supporting a complete and accurate understanding of system architecture. With integrated GenAI-powered insights, teams can accelerate decision-making, improve project planning, and reduce the time required to analyze critical systems. The platform also helps protect business operations by allowing teams to assess and predict the impact of code changes before they are implemented. This approach reduces uncertainty, minimizes risk, and supports safer modernization of COBOL environments. It provides a more intelligent and controlled way to manage, maintain, and evolve mission-critical applications.

As the demand for high-quality, dependable, and secure software grows in the face of increasingly intricate code structures, traditional debugging and testing techniques are becoming less effective. Automated tools like static source code analyzers are particularly adept at detecting flaws that might result in serious problems, such as buffer overflows, resource leaks, and other security vulnerabilities that often remain hidden from standard compilers during routine builds, runtime assessments, or normal operating scenarios. These often-overlooked defects highlight the shortcomings of conventional approaches. In contrast to other isolated source code analyzers, DoubleCheck distinguishes itself as a cohesive static analysis tool integrated within the Green Hills C/C++ compiler. It employs sophisticated and efficient analysis algorithms that have been meticulously honed and validated through over thirty years of experience in creating embedded tools. By utilizing DoubleCheck, developers can perform compilation and defect analysis simultaneously in a single process, which not only optimizes their workflow but also significantly bolsters the integrity of the code. This comprehensive method not only streamlines the development process but also enhances the ability to identify potential issues before they escalate. Ultimately, the integration of such advanced tools is crucial for maintaining high standards of software quality in today’s complex programming landscape.
