BMC AMI DevX Code Insights helps developers see how code behaves, refactor it into manageable pieces, and convert only the modules that change often enough to justify the investment. Everything else stays in COBOL.
See it. Know it. Change it.
Understand unfamiliar code fast
Right-click any COBOL, PL/I, JCL, or Assembler program for a natural-language explanation. Runtime Visualizer records the program as it runs and charts every program and I/O call in sequence, so developers see how the application behaves before they change it.
Bring new developers onto the mainframe
Natural-language explanations and formal specifications carry the business logic, so developers without a COBOL background read and maintain the code. New hires reach productivity in 4.5 months instead of 9.
Change complex code faster
Developers see how a program behaves before they touch it, then complete code changes 33% faster.

Understand before you convert: the ABC Method
Conversion-first tools translate COBOL line by line and carry the original structural problems straight into the Java. BMC runs the other order through Adaptive Business Code Evolution, the ABC Method: Analyze, Build, Convert.
Prepare the architecture
Analyze: Runtime Visualizer and Code Insights Program Requirements map how programs execute and generate formal specifications that capture business rules and functional intent. Build: Code Extract refactors monolithic programs into modular, reusable components with clean interfaces, so the architecture improves before any language changes.
Transform what earns it
Convert: GenAI COBOL-to-Java Conversion targets the modules that change most often, produces well-documented Java with proper error handling and object-oriented design patterns, and validates output against business intent rather than line-by-line equivalence. The incremental path: Convert what earns it, keep the rest in COBOL, and preserve the business logic at every step.

Use cases
Onboard a developer who inherited unfamiliar code
A new developer joins the team and inherits a COBOL application nobody has touched in years. BMC AMI Assistant explains the code in natural language with a right click, and the developer inserts those explanations as inline comments for the next person. No waiting for the one engineer who wrote it.
Refactor before a major release
A monolithic program needs changes but the risk of breaking dependent logic is too high. Code Extract isolates the affected logic into a new, ready to compile subprogram that can be modified and tested independently, without restructuring the entire application.
Trace a production issue across programs
An application fails and the team needs to understand the execution path. Runtime Visualizer replays the execution trace, every program and I/O call in sequence, without requiring access to source code, so the team sees where the issue occurred.
