Core capabilities
Architecture for source-backed COBOL knowledge.
COBOLpro ingests source artifacts, resolves dependencies and topology, stores evidence in a reviewable artifact layer, and exports documentation for teams and approved AI tools.
Source ingest
Bring COBOL programs, copybooks, JCL, scheduler metadata, DB2 schemas, VSAM layouts, interface notes, and operational files into one governed intake with the original source evidence preserved.
Inventory normalization
Normalize artifacts into a portfolio inventory with system ownership, version history, source locations, evidence links, review status, and the metadata teams need before analysis starts.
Parsing and static analysis
Parse COBOL and job artifacts, expand copybooks, trace control flow, identify calls, and capture file, table, screen, and transaction access without relying on tribal knowledge.
Dependency and topology resolution
Resolve call paths, job flows, copybook reuse, program-to-job relationships, file and table dependencies, interface touchpoints, and lineage into a topology reviewers can inspect.
Business rule and data lineage extraction
Extract calculations, validations, thresholds, branching logic, data movement, and field-level lineage into rule catalogs with source citations attached to each claim.
Evidence-backed documentation outputs
Generate runbooks, architecture maps, data dictionaries, rule catalogs, impact views, and reviewer-ready documentation with evidence links back to programs, copybooks, jobs, files, and tables.
Review, approval, and export
Route artifacts through SME review, approval status, comments, and audit trail, then export to Confluence, PDF, JSON, APIs, internal knowledge bases, and AI-ready bundles.
One product, three jobs
Modernization, rule extraction, and enterprise documentation in the same platform.
COBOLpro produces a shared knowledge base for analysts, developers, auditors, architects, and delivery teams instead of splitting context across point solutions.
01
Modernize legacy code
Migrate or refactor COBOL with the full picture in hand.
Dependency maps, impact paths, rule catalogs, data lineage, and runbooks give change teams the evidence they need before migration, wrapping, refactoring, or retirement work begins.
02
Business rules extraction
Pull every rule out of COBOL and trace it to the source.
COBOLpro identifies calculations, validations, thresholds, exceptions, policy logic, and control paths, then connects each rule back to the exact source artifacts reviewers need to inspect.
03
Enterprise documentation
Centralize knowledge across thousands of programs.
The same pipeline scales across portfolios with approvals, ownership, review status, exports, and evidence packages for regulated, multi-team COBOL estates.
Enterprise documentation model
Two views, one source of truth.
Deterministic source-backed documentation, reviewer-friendly explanations, and exports that fit your approved AI and documentation stack.
01
Business analyst view
Plain-language processes, rules, exceptions, data meaning, ownership, controls, and open questions for business, audit, and operations stakeholders.
02
Developer view
Program flow, paragraphs, copybooks, JCL, call trees, files, tables, dependencies, lineage, and source references for engineers maintaining or changing COBOL.
01
Deterministic documentation first
Documentation is generated from parsers, static analysis, dependency resolution, and source evidence. The same source produces the same artifact structure every time.
02
LLMs are optional explanation layers
AI is used to phrase explanations, summaries, and search answers on top of source-backed artifacts. It is not the system of record for rules, lineage, or documentation truth.
03
Bring any LLM you want
Export to the model and workspace your enterprise already approves: commercial LLMs, private models, Copilot-style tools, RAG systems, Confluence, PDF, JSON, or internal knowledge bases.
