Product / Business rules extraction
Pull every rule out of COBOL and trace it to the source.
Extract calculations, thresholds, validations, exceptions, and policy logic from COBOL into a reviewed rule catalog that business analysts and developers can use together.

From overload to actionable insight
A live rule monitor for hidden COBOL behavior.
COBOLpro treats rule extraction as source analysis first. The platform identifies where behavior lives, groups related logic, and gives reviewers a clean way to confirm meaning without losing the source trail.
01
Business analyst view
Read what the rule does, which policy it supports, what data it depends on, and where exceptions are handled.
Rule lineage
See which input fields, files, copybooks, jobs, and downstream reports depend on each business rule.
02
Developer view
Inspect the exact paragraphs, conditions, copybooks, tables, and data movement that support each extracted rule.
Reviewer workflow
Mark rules as confirmed, disputed, deprecated, high-risk, or ready for migration with owner notes attached.
Surface, review, catalog
From buried logic to a reviewable rule system.
Surface
Run source analysis across programs, copybooks, and files to identify every calculation, threshold, validation, and exception branch with its source location.
Review
Assign rules to owners, confirm meaning, link evidence, flag disputes, and capture uncertainty before the catalog is used for migration or compliance.
Catalog
Export source-backed rules with owner notes, confidence status, and lineage references for analysts, developers, and audit teams.
Rule examples
Catalogs for the decisions teams actually make.
01
Eligibility rules
Thresholds, exclusions, exception handling, and status transitions.
02
Pricing and fee logic
Calculations, tables, rounding behavior, overrides, and limits.
03
Claims and payments
Validation paths, hold reasons, approval gates, and audit controls.
04
Compliance controls
Rule evidence, reviewer notes, lineage, and audit-ready export fields.
AI posture
Any LLM can explain the catalog.
Use the model your enterprise approves to summarize rules, answer questions, or generate stakeholder-specific explanations. The rule source of truth remains deterministic.
