Decode COBOL programs and JCL jobs. Extract business rules, visualize dependencies, and accelerate modernization with deterministic analysis.
Legacy mainframe systems contain decades of undocumented logic, complex dependencies, and implicit execution rules. Manual inspection is time-consuming, error-prone, and risky.
Understand large COBOL codebases through precise analysis of logic, calls, and data usage.
Automatically extract call and data dependencies between COBOL modules, copybooks, and programs.
Identify unreachable or unused code blocks that add maintenance risk without value.
Measure structural complexity to prioritize refactoring and modernization efforts.
Understand how batch jobs really execute: step order, conditions, dataset usage and control flow across jobs.
Extract execution order, return code conditions and dependencies between steps automatically.
Track dataset creation, usage and reuse across steps and jobs — including conditional references.
Generate clear diagrams showing how jobs actually run under different execution scenarios.
