Documenting Mainframe & OpenVMS COBOL

Documenting Mainframe & OpenVMS COBOL with Clarity

LegacyMap is built to handle the complexity of real-world COBOL systems—whether they run on Mainframes or OpenVMS. These applications often span decades of business logic, procedural code, file-based operations, and embedded SQL, with little to no formal documentation. We change that.

With full support for COBOL dialects used across IBM Mainframe and OpenVMS environments, LegacyMap automatically extracts system architecture, procedural flow, and data access logic. From CALL hierarchies to embedded SQL operations, we generate structured, searchable documentation your team can actually use.

Complete COBOL Understanding, No Guesswork

• CALL Tree Generation – Visualize caller-callee relationships across main programs, subprograms, and external routines.

• File and Copybook Parsing – Identify 01-level structures, COPYBOOK dependencies, and file access logic, even in sprawling legacy codebases.

• Embedded SQL Mapping – Detect and map SELECT, INSERT, UPDATE, and DELETE statements in Oracle, Postgres, and Rdb embedded SQL blocks.

• Platform-Agnostic Output – Whether your COBOL runs on z/OS or OpenVMS, LegacyMap provides clean documentation in HTML, PDF, or LaTeX formats.

Why It Matters

• Preserve Mission-Critical Knowledge – Document systems that power banking, insurance, logistics, and government infrastructure—before knowledge is lost.

• Accelerate System Modernization – Lay the groundwork for safe, successful migrations by understanding architecture and data access up front.

• Simplify Maintenance & Support – Reduce reliance on tribal knowledge and manual code tracing with structured, visual insights.

• Enable Better Collaboration – Help analysts, developers, and auditors speak the same language using standardized, shareable documentation.

LegacyMap connects the dots in your COBOL systems—across Mainframe and OpenVMS—so you can move forward with full confidence in what’s behind the code.
