Legacy COBOL systems often lack up-to-date documentation, making them difficult to maintain or migrate. LegacyMap solves this by automating the generation of accurate, detailed documentation that reflects the current state of your system. This reduces operational risk, improves code maintainability, and accelerates digital transformation initiatives involving legacy technologies like COBOL, FORTRAN, BASIC, and embedded SQL.

LegacyMap produces cross-referenced technical documentation in HTML, PDF, and LaTeX formats, compatible with Doxygen workflows. Outputs include callgraphs, file access mappings, procedure trees, and SQL access flowcharts. This documentation is fully searchable and ideal for developer onboarding, system audits, and modernization projects.

Absolutely. LegacyMap is designed to work across OpenVMS COBOL (including VAX and Alpha systems) and Mainframe COBOL running on z/OS. The tool accommodates platform-specific dialects and embedded SQL formats, giving IT teams a unified documentation workflow for legacy infrastructure. Whether you’re rehosting to Linux or preparing for cloud modernization, LegacyMap delivers the insights you need.

Yes. LegacyMap extracts and visualizes embedded SQL operations such as SELECT, INSERT, UPDATE, and DELETE from COBOL and Pro*COBOL code. It maps SQL table access by program and procedure, making it easier to audit data interactions, refactor database logic, or prepare for migrations to PostgreSQL, Oracle, or cloud-native databases.

LegacyMap is a software tool that automatically generates structured documentation from legacy COBOL applications, including those running on Mainframe and OpenVMS platforms. It analyzes COBOL source code to produce detailed callgraphs, SQL access diagrams, and procedure maps—without requiring any changes to your original code. LegacyMap is ideal for teams looking to modernize, audit, or maintain legacy COBOL systems while preserving institutional knowledge.
