GnuCOBOL
A free COBOL compiler
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. Build COBOL programs on various platforms, including GNU/Linux, Unix, Mac OS X, and Microsoft Windows. GnuCOBOL has also been built on HP/UX, z/OS, SPARC, RS6000, AS/400, along with other combinations of machines and operating systems. Copyright 2001-2024 Free Software Foundation, Inc. The cobc compiler is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the FSF; either version 3, or (at your option) any later version.

RecordEditor
Editor for Fixed Width, Csv and Existing Xml files.
The RecordEditor is a Data File editor for Flat Files (delimited and fixed field position). It supports Unix / PC / Legacy (e.g. Mainframe) file formats, both Text and binary files. The Editor uses a Record-Layout description to format the files. This is ideal for Fixed width (Text or Binary) files, Cobol Data Files, Mainframe files and complicated Csv files. Cobol Copybooks can be used to format Cobol Data files. As well as an editor, The following utilities are supplied * Formatted Compare * File Copy and reformat Utility * FileWizard this is use to work out the format of a File. It can generally find both Text and binary / packed deicimal fields in a file For Simple Csv you should look at its sister project reCsvEditor. Note: The core Editor code is also used in the "Protocol buffers editor" and "Avro Editor" -

Applewood Computers Accounting System
Accounting system for smaller companies written in GnuCobol.
ACAS contains Sales, Purchase and Nominal Ledgers (Accounts Receivable, Payable and General Ledgers) as well as Stock Control (Inventory Control) along with IRS (Incomplete Records System). This system is written in COBOL and uses the free GnuCobol compiler which compiles via C code and is therefore compatible with the following platforms: Linux, Unix, Dos, Mac OSX, Windows providing you have installed the GCC C compiler or an equivalent as well as GnuCobol. at a minimum, v2.0+. Note that all testing is done using v3.2. The current version utilises standard Cobol files, be they sequential or indexed. The beta version, offers additional support for Mysql and Mariadb. This is available as v3.3 and as a nightly build direct from the lead programmer. -

COBOL Utilities Project
All in, COBOL
COBOL Utilities Project collects free and open-source COBOL utilities, libraries, and test suites, which are independent of any specific COBOL compiler. COBOL-UP supports free and open development. A teamwork discussion group has been established. Threads will be focused, the forum open to any and all COBOL. Developers are encouraged to signal interest in write permissions, as this will be an open to all, COBOL utility project. Mainframe, mid-range, Mac, PC, Hercules, Raspberry. Signal interest, we'll set you up with some (vetted) file, distribution and communication space. Wildcat, GnuCOBOL, Micro Focus, Elastic, RainCode, IBM, Tiny COBOL, all the others, all in. COBOL-UP -

EDITEL
EDITEL is a screen editor/code generator for GnuCOBOL programmers
One of the hardest things to do when coding with COBOL is translating a screen design into code. The process may take hours, not to say days. In my old BLIS-COBOL, COBOL 74 and COBOL 80 /85 days (and those last 2 had the SCREEN SECTION which helped a lot !), I recall spending a significant amount of time dedicated to that activity. Time that could be used for more productive activities like coding and resolving bugs, for instance. Having said that, I developed a Screen Editor (similar to a Screen Painter, as some tools may call it) which allows the user to create screen layouts (which includes the use of colors) with delimited fields and respective input masks, and finally generate the SCREEN SECTION code that reflects that layout. All of it automatically - no code needed. The idea came from a program I used to use named EDITEL. I have adapted the concept (it was originally built for BLIS COBOL systems) and created a version that does this for GnuCOBOL and Microfocus COBOL. Enjoy ! -

lixa
LIXA, LIbre XA, is a free and open source XA transaction manager
LIXA (LIbre XA) is an open source and free Transaction Manager implementing the distributed transaction processing "XA specification" and "TX (transaction demarcation) specification" according to the X/Open CAE Specification. LIXA implements even XTA: XA Transaction API, an innovative API that implements XA transactional context passing among different applications. LIXA is a Transaction Manager but it's not a Transaction Monitor: this is the distinguishing feature of the project. LIXA technology enables every application container, like a web server or a shell, to become a two phase commit application server. The client/server architecture of LIXA allows many application containers to share a single LIXA (state) server: this is ideal when horizontal scalability is a must and many identical application containers must refer to a single transactional environment. LIXA can be used with the C, C++, Java, Python and COBOL programming languages. -

Cobol Projects
Personal Cobol projects that may be of use or interest to others
This repository is for personal Cobol projects. The projects are stored here in the event someone needs to look at Cobol code for any reason. Most, if not all, of the code was created for personal projects and not professional use. Nevertheless, if the code is useful, feel free to download a copy and use in your own projects. -

Cobxref
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. it is used as a stand alone program. This version includes the code from printcbl which takes in the copy books when used by any COPY verbs in the source. See the readme file for more info. This program is also in the GNUCobol SF area under contributions/tools -

The Flight Log software allows all flight crews, Pilots, Flight Engineers, Reo’s and other GIB’s etc, to record their flight time in a unified location namely their computer, regardless of platform, i.e., Linux, OSX, and other *nix systems as well as Windows. This is the only purpose of Flightlog, it does not do other functions such as flight planning, weight and balance etc as there are plenty of tools around if needed, to help do these functions. The OS (Open Source) version allows users to install the free Cobol compiler, build and run all self tests and then compile (or build) the Flightlog program.
