Fujitsu NetCOBOL
Solution overview
Fujitsu NetCOBOL is a complete COBOL compiler and runtime environment for Windows, Linux and .NET platforms. It lets organisations move applications off the mainframe and other legacy environments onto modern infrastructure without rewriting code — preserving business logic proven over decades of operation, along with existing team skills. The source code remains the customer’s property, and distributing finished applications carries no runtime fees, significantly lowering total cost of ownership.
Key benefits
Modernisation without rewriting
Migrate COBOL applications to Windows, Linux or .NET while retaining existing business logic.
No runtime fees
Deploy applications without additional licensing, for predictable and lower TCO.
Integration with a modern stack
Interoperate with C#, VB.NET, web services and ASP.NET; code executes under the .NET CLR.
Familiar development tools
Eclipse-based NetCOBOL Studio and Microsoft Visual Studio, with full debugging support.
COBOL standards compliance
Stable operation of critical systems and full reuse of existing code and skills.
Reduced vendor lock-in
You own the source code, and applications fit naturally into DevOps and CI/CD pipelines.
