GnuCOBOL (formerly OpenCOBOL) is a free, modern COBOL compiler. GnuCOBOL implements a substantial part of the COBOL 85, X/Open COBOL and newer ISO COBOL standards (2002, 2014, 2023), as well as many extensions included in other COBOL compilers (IBM COBOL, MicroFocus COBOL, ACUCOBOL-GT and others).
GnuCOBOL translates COBOL into C and internally compiles the translated code using a native C compiler.
CB2XML (CopyBook to XML) is a COBOL CopyBook to XML converter written in Java and based on the SableCC parser generator. This project includes utilities to convert an XML instance file into its COBOL copybook equivalent string buffer and vice versa.
Source is now available in GitHub: https://github.com/bmTas/cb2xml
Cobol Cross reference tool for GnuCobol written in Cobol
CobXRef is a Cobol cross reference tool that reads a Cobol source program and produces a file suitable for printing 'as is' that contains all variables, procedure paragraphs and section names referenced where they are defined
as well as where they are used throughout the program or module as well as lists of unreferenced data names and paragraph & section names.
AppSignal's MCP server hands Claude, Cursor, or Zed your real errors, traces, and the deploy that shipped them. AI writes the fix; you review the diff.
A general purpose source code indexer and cross-referencer that provides web-based browsing of source code with links to the definition and usage of any identifier. Supports multiple languages. Up-to-date information in http://lxr.sourceforge.net
**CAUTION!** Releases are now issued on Codeberg due to legal reasons. See https://codeberg.org/ajlittoz/CB_LXRsource/releases
A COBOL debugger for GnuCOBOL/OpenCOBOL written in GnuCOBOL
A COBOL debugger for GnuCOBOL written in GnuCOBOL. Works with both current GnuCOBOL and old GnuCOBOL/OpenCOBOL 1.1; could be used for other vendors with slightly modifications, too.
Take a look at https://gnucobol.altervista.org/tp-cobol-debugger/
This project has moved to GitHub ! The version here at SourceForge will remain for historic purpose.
Koopa is a parser generator, made for COBOL. It can handle source files in isolation (no preprocessing required) and doesn't mind the presence of CICS/SQL fragments. The grammar is easily extensible in a way which minimizes the impact on the overall code.
The cobcurses project has moved to github.com. Visit https://github.com/ve3wwg/cobcurses for all future project updates and documentation.
This project consists of a Cobol interface to curses(3X) using a Screen Designer utility. This project is being developed for use with the Open-Cobol compiler project.
RES is a pure Java based Open Source Cobol to Java translator. It creates maintainable Java code for a subset of VS Cobol syntax. It has been developed with JDK, JTB and Javacc.
Stop Cyber Threats with VM-Series Next-Gen Firewall on Azure
Native application identity and user-based security for your Azure cloud
Gain integrated visibility across all traffic in a single pass. Deploy Palo Alto Networks VM-Series to determine application identity and content while automating security policy updates via rich APIs.
Java Cobol Lexer take a cobol source program and return it as a list of lexical tokens.
Library takes source code in fixed, free and mixed formats. It recognizes standard Cobol 85.
A compiler and cross-compiler for (Currently) Cobol (with Fortran being added later). It is intended to be the first self-hosted open-source Cobol Compiler, e.g. the compiler itself will be written using Cobol.
Add-on for the WSDL2... utility from the Apache Axis project, this utility will read WSDL files and generate COBOL copybooks and source code appropriate for marshalling and unmarshalling XML messages.
