SuperBOL Studio

SuperBOL Studio is a set of powerful tools to help COBOL developers maintain and improve COBOL software, bound together in a Vscode extension.

SuperBOL Studio features powerful edition and navigation in COBOL projects using an LSP (Language Server Protocol) for COBOL, debugging and profiling modes for COBOL applications, and linting and analysis of COBOL sources.


GnuCOBOL is an open-source project started in 2005 (formerly OpenCOBOL), to provide a free industry-ready compiler for COBOL. It supports most of the mainstream COBOL dialects and features, and is portable to most platforms and operating systems.

OCamlPro has been contributing actively to the development of GnuCOBOL since January 2022 for its customers, fixing bugs and contributing language extensions.
