Make your COBOL readable for decision-makers
In seconds, see who calls what, which files/tables are impacted, and where risks concentrate. Ideal for prioritizing workstreams, cutting mainframe costs, and meeting audit requirements (GDPR, SOX, Basel III).
Clarity
Dependency map: JCL ➝ Programs ➝ Copybooks ➝ Files/Tables. It’s the org chart of your COBOL landscape.
Faster decisions
Identify critical modules, estimate change impact, and prioritize actions (optimization, testing, modernization).
Compliance & audit
I/O flow traceability and data lineage: prepare audits (GDPR, SOX, Basel III) without reading 30,000 lines of code.
Demo — Interactive Mini Call Graph
This prototype shows an example. In the integrated Bosqweb version, the graph is automatically generated from your COBOL programs, JCL, copybooks, and file/DB access.
1) Upload & scan
Upload COBOL/JCL/Copybooks → extract dependencies (calls, reads, writes).
2) Visualization
Interactive graph + glossary (Program • JCL • Copybook • File) for decision-ready reading.
3) Action
Module prioritization, impact estimation, progressive roadmap (testing, modernization, zIIP).
