OL AtomIQ
Analyze COBOL, RPG, PL/I, Natural, JCL, and other legacy applications to uncover dependencies, data flows, and business operations.
OL AtomIQ is OpenLegacy's legacy language intelligence platform, designed to analyze and understand applications written in COBOL, RPG, PL/I, Natural, JCL, Easytrieve, and other enterprise legacy technologies.
By automatically discovering business entities, operations, dependencies, data flows, and application relationships, OL AtomIQ provides the visibility required to accelerate modernization initiatives, reduce project risk, and preserve critical institutional knowledge.

Key capabilities
-
AS/400
AS/400 (IBM i) & RPGRun AtomIQ as a first-class IBM i platform: JT400 import, DB400, DSPF map preview, and RPG analysis pipeline alongside COBOL.
-
COBOL
Data LineageTrace data from DB2 columns, IMS segments, and file fields through COBOL host variables across programs and copybooks.
-
AI
Graph Assistant & MCPIn-app graph-aware AI chat plus a built-in MCP server so assistants can read and drive AtomIQ workspaces programmatically.
-
COBOL
IMS COBOL and MFS mapsAnalyze IMS-DC COBOL and MFS maps in AtomIQ: preview device formats, classify CBLTDLI screen vs segment calls, and walk conversational UI flow from source.
-
CICS
Interactive App ViewerDrag-and-drop canvas to organize programs into apps by business usage, visualize dependencies, filter, and persist workspaces.
-
AI
Map UI analysis → Hub terminal Screens FlowFrom COBOL plus BMS or MFS maps, analyze the UI state machine in source. For CICS + BMS, build an OL Integration terminal Screens Flow. AtomIQ shows maps and analyzes source; it does not run a live terminal.
