Understand Your Legacy: Code Analysis & Automated Documentation
FAQ Categories
De-Risk Your Migration
LegacyScan identifies 100% of OpenVMS API usage and non-portable extensions, while LegacyMap generates vital documentation, providing clarity before you modernize.
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.
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.
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.
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.
Legacy environments often lack visibility. LegacyScan bridges that gap by automating insight into structure, risks, and dependencies.
Absolutely. Our scan is read-only and non intrusive.
Yes, LegacyScan has multiple phases. Phase 1 is to scan the OpenVMS 3GL or SQL and map the non portable elements against the Sector7 language remediation tools. Sector7 have language remediation tools for all the major OpenVMS languages (C, BASIC, COBOL, FORTRAN, PASCAL, SQL, SQLMOD). If any extensions are detected that are not handled by the Sector7 language remediation tools a JIRA is created for that specific issue and the tool set enhanced.
Yes. LegacyScan detects all use of DCL verbs and syntax. It even follows logicals and symbols through various operations and attempt to reconstruct the values and thus the values passed to the various dcl verbs. LegacyScan will detect all DCL use the is no supported by Sector7's VX/DCL - our 100% compatible implementation of OpenVMS DCL for Linux.
Yes, LegacyScan will detect the use of SMG, FMS and DEC FORMS. All 3 are supported in the Vx/Tools migration toolkit.
Yes, LegacyScan will detect and document the use of all system calls that use the asynchronous capability such and $QIO, $QUI ec Vx/Tools supports IO to devices via the QIO interface with asynchronous even completion (and event flag notification).
Yes, LegacyScan and the Vx/Tools migration tool kit support over 1000 OpenVMS system service calls - SYS$, LIB$, CLI$, SOR$, STR$, SMG$, FDV$, FORMS$ etc .
Yes, LegacyScan and Vx/Tools migration tools kit supporters over 4000 flags to various OpenVMS system services - for example - we support all of the flags to RMS FAB / RAM / NAM / XAB blocks - and we support RMS files. Any flags that LegacyScan find that are not in its database of supported flags is highlighted and placed into an exception report.
LegacyScan produces fill code and OpenVMS usage analysis reports including detailed exception reports. Exception reports being generated when LegacyScan find the use of an OpenVMS capability that it cannot match in its internal database. LegacyScan's database is a real time mirror of the function of the Vx/Tools migration tool kit.
LegacyScan is Sector7's analysis tool that provides detailed assessment of your legacy systems. Learn more about our assessment process and the insights LegacyScan can provide for your migration planning.
Sector7 offers a free code assessment to evaluate your migration requirements and provide initial project insights. This assessment helps identify potential challenges and opportunities before your migration begins. Get in touch to schedule your free assessment.
