- A free COBOL Compiler with all the features and cross-platform ready. Community help is also exceptional. Thank you all.
- GnuCOBOL (formerly OpenCOBOL) is a great project, highly recommended.
- A very interesting and useful Project. I used this Compiler with a lot of fun.
- After writing in Cobol since my TI 990 days and then HP UX Cobol, RM and Micro focus I was excited to use to GNUCobol. After 2 days of dealing with all of the OpenCobolIDE meaningless compiler error messages and the lack of GNUCobol maintaining any ANSI Cobol standards I finally gave up. The Cobol language, in my opinion, is still one of the finest for business applications but this GNUCobol application is absolutely horrible. Looks like a bunch of amateur C++ programmers tried to write a Cobol cross compiler without understanding how Cobol should be written.
Reply from GnuCOBOL (formerly OpenCOBOL)
Posted 2018-12-16Looks like you have not specified `-std=cobol85` (or `-std=cobol2014`) and still expected to have a COBOL compiler restricted to this (while others expect a compiler that supports MicroFocus or Fujitsu or ...). As GnuCOBOL passes nearly all tests of the COBOL 85 NIST tests I'd argue that 'a bunch of amateurs [...] without understanding how Cobol should be written' sounds quite wrong. You may want to use the discussion boards or mailing lists (or read the documentation) to find out how to use GnuCOBOL to get what you want.

Oct 10, 2016 I want to download a free cobol compiler for windows 10 that works. Any suggestions? Hi Brutis4246, 'I want to download a free cobol compiler for windows 10 that works. Any suggestions?' If you want to compiler COBOL on Windows, you could download and use GnuCOBOL (formerly OpenCOBOL). You also could study COBOL and write COBOL code online.

This page lists free implementations of the COBOL language,whether they follow the ANSI 85 COBOL standard, ANSI 74 COBOL standard, ANSI 2002 or otherwise.COBOL, or the 'COmmon Business Oriented Language', is a programming language used in the earlier days of computing to writemany business (hence its name) and financial programs. It continues to be used today in certain systems. The COBOL 2002ANSI standard added many modern programming language features to the language, including object-oriented syntax, user-defined functions,pointers, and so on.

GNU Cobol (formerly OpenCOBOL) implements 'a substantial part of the COBOL 85 and COBOL 2002' standards along with many of the vendor extensionsused by other COBOL compilers (such as those by MicroFocus, IBM, MVS and BS2000). It translates the COBOL code to C, whichcan then be compiled using the system's native C compiler (such as the GNU C compiler onLinux systems). Platforms supportedinclude Windows, POSIX systems such as Linux, thevarious BSD OSes, OpenSolaris, and Mac OS X.The compiler passes many of the tests included in the National Institute of Standards and Technology (NIST) COBOL 85 test suite, althoughit does not claim conformance to any level of the COBOL suite. With the use of standard I/O redirection, you can also use the code generatedby the compiler in CGI programs. It is released under the GNU licences (GPL and LGPL). At the time this is written, the compiler isavailable in source form only (that is, you need to compile it yourself).
This is an attempt at creating a COBOL 85 compliant compiler for Linux and otheroperating systems. It generates assembler code which is passed to the GNU C compiler backend.At the time of this writing, the work is still not completed (it can only generate code for a'very small subset of COBOL'), but the source code is accessible for you to tinker with.
The Wildcat Cobol Compiler for .NET, Mono (an open source implementation of .NET) and DotGNU Portable .NET runtimes, is an open source COBOL compiler with someextensions that allow your programs to use the .NET Framework and external .NET assemblies such as NUnit. The compiler is released under the GNU GPL.
(Update: this project is no longer being updated.)This COBOL implementation intends to be compliant with COBOL 85 standard, in particular,according to their website, the ISO 1985, ISO 1989-1 (Intrinsic Function Module),ANSI X3.23-1985, ANSI X3.23a-1989 (Intrinsic Function Module), X/Open XPG3(COBOL programming languages extensions). It has, in addition, the ability to read/write fromstandard input/output/error, read command line parameters, read environment variables, seta file name at runtime, and return a program exit code to the invoking process.It generates Intel x84 assembly language code, and works together with the GNU assembler togenerate binaries. Platform supported: Linux. The compiler is licensed under the GNU GPL.
Free Cobol Compiler For Windows
Micro Focus Visual COBOL Personal Edition has two versions: the Visual Studio one allows you to create COBOL programsthat run under either the .NET Framework, and the Eclipse version generates code for aJava Virtual Machine.Note that although it is listed on this page alongside other free COBOL compilers, itis actually only a 1 year trial. You have to register with them (giving them your name and contact details)for a 365-day student licence. Nonetheless, I'm listing it here because their site says that when your trial expires,you can just re-register again for another trial licence. Be sure to read their licence agreement to find out whatyou are allowed to use the product for; I was unable to access that document at the time I wrote this (the link was broken).Platforms supported include Windows and Linux.
This is a 16-bit COBOL compiler for DOS and Windows. It supports some of the ANSI74 specifications, lackssome features like SORT and STRING, and includes other non-standard features such as the modules that allowscreen output. Compiled programs use video mode 12h, a 16 colour graphical mode with a resolution of 640x480.The compiler comes with an IDE, linker, a runtime module and a reference manual.
This is an old free MSDOS COBOL compiler that comes with documentation. It is no longersupported (the author was apparently dying at the time it was released). Itconforms with the ANSI COBOL-74 standard although it does not implement the sort/merge feature.It apparently generates OBJ files, so you will need a linker to generate an executable binary.You can get free linkers from the Free Assemblers, Linkers and Object Module Librarians page.

This is a very old freeware versions (version 0.001 Apha) of the Deskware COBOL interpreter. The interpreter supports a subset of the ANSI85 COBOL syntaxand has some extensions. Alas, the package does not come with any documentation. The freeware version is no longer supported.
