Can OpenLegacy create APIs from COBOL running on x86?

Q: Can OpenLegacy create APIs from COBOL running on x86?

OpenLegacy can assess COBOL on x86, especially Micro Focus/Rocket, but the API approach depends on whether the app exposes RPC services or screens.

Yes, in most cases. OpenLegacy supports Micro Focus/Rocket COBOL environments on x86 directly. Other COBOL runtimes, such as IBM COBOL or GNU COBOL, can often be supported as well, though the specific fit depends on the runtime and how the application is built.

What determines the approach

The COBOL runtime matters. Micro Focus/Rocket COBOL on x86 is the most directly supported environment. Other x86 COBOL runtimes are evaluated case by case.

How the application is structured matters more.

If the application exposes RPC-style services — callable programs or subroutines with defined inputs and outputs — OL Integration can typically model that logic as typed API methods directly, using RPC Flow Methods.
If the application is screen-based, exposing it as an API depends on how the screens are implemented. This usually takes more investigation up front — identifying the relevant screen maps or descriptors — before a clear API path can be proposed.

Next step

Because the right approach depends on the runtime and application structure, a short technical discovery conversation is the fastest way to confirm the details and identify the right integration path for a given COBOL-on-x86 environment.
