Cobol Software Free Download For Windows 7 64 Bit
GnuCOBOL (formerly OpenCOBOL) is a free COBOL compiler. Cobc translates COBOL source to executable using intermediate C, designated C compiler and linker. OpenCOBOL 1.1 became GNU Cobol 1.1 in 2013. GnuCOBOL 2.2 is the latest, version 3.0 is on its way. A programmer's guide, by Gary Cutler and Vincent Coen, is indexed at together with more documentation.

GnuCOBOL (formerly OpenCOBOL) is a free COBOL compiler. The GnuCOBOL 'cobc' program translates COBOL source code to into C code, and then uses a local or embedded C compiler to translate the intermediate C code into executable programs. This page includes free downloads of ready-to-install copies of GnuCOBOL for Windows. These versions were built with 32-bit MinGW (Minimalist Gnu for Windows).
There are three versions of 32-bit MinGW GnuCOBOL 3.1-dev (28Aug2019) for Windows XP, Vista, 7, 8/8.1, and Windows 10. One is built with Oracle Berkeley Database for indexed sequential file support (ISAM), one with no ISAM support, and one with VBISAM 2.01 for ISAM support. Some users may find the Oracle Berkeley Database license too restrictive for redistribution of COBOL executable programs. All three versions may be downloaded below.
For anyone who would like to build GnuCOBOL 3.1-dev (or other versions of GnuCOBOL/OpenCOBOL) using MinGW (Minimalist Gnu for Windows), there are build guides available for download in both PDF format and LibreOffice ODT format (which can be edited with MS Word or OpenOffice Writer). 32-bit MinGW is a minimal unix-type environment for Windows that allows you to build the GnuCOBOL compiler using GCC (the Gnu Compiler Collection). The generated GnuCOBOL compiler runs in a normal Windows CMD.EXE shell, similar to the old MS-DOS command.com window. GnuCOBOL uses an embedded version of MinGW GCC to compile intermediate C code into executable code.
As of 13JAN2018 I have added a manual (revised 31MAY2018) on Using MinGW GnuCOBOL, including how to install GnuCOBOL (and OCIDE), how to compile programs, and how to prepare GnuCOBOL applications to be installed on a target Windows PC without installing the compiler.
There is also a link to Colin Duquesnoy's OpenCobolIDE, which is a free, open source GUI Interactive Development Environment (IDE) for GnuCOBOL written in Python for GNU/Linux, Windows, and Mac OSX. The Windows installer includes GnuCOBOL 2.0 Release Candidate 2 in addition to the IDE. This is probably the quickest way to install a working COBOL compiler for Windows. You can also change the Preferences in 'OpenCobolIDE' to use an alternate version of GnuCOBOL, even the 64-bit MinGW GnuCOBOL or an MS Visual Studio build.

GnuCOBOL Compiler install binaries
Here are the newest MinGW GnuCOBOL 3.0 download files built with MinGW Gnu Compiler Collection 6.3.0. and packaged as 7-Zip self-extracting files. The revised versions of GnuCOBOL 3.0 Release Candidate 1 now include PDCurses 4.0.2/win32, instead of PDCurses 3.4. The '.exe' file extensions were renamed to '.7z' to comply with my web host's safety rules. These files are smaller than previous binary downloads after removing unneeded elements and adding improved 7-Zip compression. They can be extracted using the open source 7-Zip alternative to Windows built-in ZIP file support. You can also rename the file extension from .7z to .exe to use them as 7-Zip self-extracting archives.
Building GnuCOBOL with VBISAM is challenging. The best version of VBISAM I have found is 'VBISAM 2.01' but it is not hosted where it can be easily found. It is based on VBISAM 2.0 by Roger While from the VBISAM SourceForge project. But it has been patched by Sergey Kashyrin, Mario Matos, and an anonymous poster in the GnuCOBOL SourgeForge discussion forums. So I am hosting it here in two different files.
(NEW 2019-05-11) 64-bit MinGW GnuCOBOL 3.0-rc1.0 for Windows
With many thanks to Simon Sobisch, the GnuCOBOL project leader, you can now build a MinGW 64-bit version of GnuCOBOL 3.0-rc1.0 for Windows, which includes gmplib, ncurses, and Berkeley DataBase. This version was built with MSYS2/MinGW 64-bit, and includes GCC 7.3.0 as the embedded C Compiler. You can download the binary which was compressed with 7-Zip and rename the file extension from '7z' to 'exe'. Then you can run it as a self-installed archive. Open a cmd.exe window in the install folder, and run 'bincobenv -v' to set the environment variables. There is also a link for the 64-bit build guide in LibreOffice ODT format and in PDF format. I have tested using OpenCobolIDE 4.7.6 with this 64-bit GnuCOBOL compiler
Older GnuCOBOL/OpenCOBOL Downloads
Gary Cutler's OpenCOBOL 1.1 (06FEB2009) is available for download below as a packaged installer for Windows XP/Vista/7/8.
Some time ago I built the GnuCOBOL 1.1 compiler (20JAN2014) using source code available from the GnuCOBOL/OpenCOBOL project on Sourceforge.net. The compiler has been tested with the GnuCOBOL version of the NIST (National Institute of Standards and Technology) COBOL85 test suite and passes 9,011 out of 9,129 test cases. Please see the link below for a Windows installer for GnuCOBOL 1.1.
There are three versions of MinGW GnuCOBOL 2.0 Release Candidate 2 (06NOV2016) for Windows XP, Windows 7, Windows 8.1, and Windows 10. One is built with Berkeley Database for indexed sequential file support (ISAM), one with no ISAM support, and with VBISAM 2.0 for ISAM support. Some people may find the Berkeley Database Oracle license too restrictive for redistribution of COBOL executable programs. All three versions may downloaded below. The newest versions are compressed into smaller download files.

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.
Avantgarde bk bt eclipse font settings 2017. 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.
