OL Next
Move COBOL and RPGLE screen and RPC programs (CICS/BMS, IMS/MFS, IBM i/DSPF) off the host as runnable code on the JVM, validate them in the browser, and expose them as REST APIs while data stays on the host.
OL Next moves legacy screen and RPC programs off the host without rewriting them. It converts COBOL and RPGLE programs, together with their CICS BMS, IMS MFS, or IBM i DSPF maps, into runnable legacy code on the JVM. Teams keep editing the original COBOL or RPGLE in OL Next, run and validate the converted programs in the browser, and expose them as REST APIs. Business logic can leave the host first, while the data stays where it is until a data migration is ready.
Key Features
-
CICS
CICS COBOL / BMS migrationConvert CICS COBOL screen programs and BMS maps into legacy code that runs on the JVM, then play the maps in OL Next.
-
API
DB access managementPoint a replatformed program at an H2 sandbox, a live host store, or a modern database, so the logic can leave the host before the data does.
-
COBOL
IMS COBOL / MFS migrationConvert IMS DC COBOL programs and MFS maps into legacy code on the JVM, and play the conversation with SPA state in OL Next.
-
AS/400
Interactive program playerRun a converted map program in the browser: fill the map, press an AID key, and read the run log.
-
API
Map screen flowsRecord or author a map screen flow with declared inputs and outputs, run and debug it against the converted program, and publish it as OpenAPI.
-
AI
MCP server for AI agentsGive an AI agent OL Next tools over MCP: import a program, convert it, run screens and RPC calls, record or generate flows, and bind a host data source.
