The COBOL programs that run your business can drive modern web, phone, and desktop interfaces — compiled by the compiler you already own, running the source you already trust. No rewrite. No new dialect. No migration project.
Works with RM/COBOL · Micro Focus (native and managed .NET) · ACUCOBOL-GT · GnuCOBOL · isCOBOL — plus our own cross-platform COBOL for shops without a vendor licence.
Every screenshot below is the same customer-maintenance program — a real Micro Focus Dialog System application, compiled with the customer's own compiler, its indexed files and business logic untouched.
The same program also runs in any web browser with nothing installed — and under the hood, one wire protocol drives every surface, including native Flutter, React Native, Java Swing, WPF and Avalonia clients. The interface layer is never the thing that locks you in.
These are not mock-ups. Each screenshot is an existing legacy screen definition — untouched — rendered live in a plain web browser, with the original COBOL program behind it reading and writing its data.
Character screens get the same treatment — terminal programs render on a clean screen canvas, cursor behaviour and all. If your screens are ACUCOBOL, Dialog System, or plain terminal COBOL, they can look like this without a rewrite.
Your vertical product wins on depth — and loses demos to SaaS competitors whose screens look current. Put a modern web and mobile interface on the product you already have, keep the business logic that took decades to get right, and open the door to hosted, subscription delivery.
The application works; the terminal screens and the shrinking bench of people who maintain them are the risk. Give the same programs a modern interface your staff and auditors recognise — and get your operational data onto phones in the warehouse, the truck, the field.
Your clients ask for modernization; the honest answers have been "rewrite it" or "live with it." MobileCOBOL gives you a third answer you can demonstrate in an afternoon — and a delivery model where your team does the work with our platform and our support.
ACUCOBOL SCREEN SECTION programs — character or graphical —
and Micro Focus Dialog System screensets run as modern UI without
source changes. A conversion path is there when you're ready to retire
the Dialog System runtime itself — your compiler stays exactly
where it is.
The bridge links RM/COBOL, Micro Focus (native or managed .NET), ACUCOBOL-GT, GnuCOBOL and isCOBOL to modern clients. One developer kit, one install, pick your compiler.
Camera, barcode and QR, GPS, signatures, biometrics, notifications — called from ordinary COBOL statements, working on phones, tablets and the browser.
Field devices lose signal. Sessions survive disconnects and resume where they left off — the COBOL program never knows it happened.
Summarize, classify, extract and translate from COBOL working storage with simple verbs — bring your own API key, keep your data path explicit.
Everything installs on hardware you control. Programs can run on-server, on-device, or fully standalone on the device — your deployment, your rules.
The fastest way to evaluate MobileCOBOL is with your own program. Send us a screenset, a SCREEN SECTION program, or just a description of what you run — we'll show you what it looks like on modern glass.
