Welcome to the OpenCOBOL Website!


opencobol.org is in a state of hibernation

GnuCOBOL, (renamed from OpenCOBOL) is currently active on SourceForge

current developments and conversations are at http://sourceforge.net/p/open-cobol/

opencobol.org will remain here for archival purposes. There is a LOT of good reading to be had here, in the discussion forum. A nice history. Treat as READONLY.
Apologies, if you just got here from SourceForge, this site is historical, and worth a read through. Current developments and chatter are happening back on the forge though.

Current activity is on SourceForge


You do not need a SourceForge account to post to Help Getting Started, but there will be a delay, pending approval by a volunteer.


OpenCOBOL accepted by GNU as GNU Cobol

There is a new GNU Cobol project, as of September 27th, 2013, on the 30th anniversary of the original GNU Usenet announcement. The spelling was then changed to GnuCOBOL, the official project name. Excuse the redirection, but, the forge is a nice place to be, and soon GNU.


OpenCOBOL is an open-source COBOL compiler. OpenCOBOL implements a substantial part of the COBOL 85 and COBOL 2002 standards, as well as many extensions of the existent COBOL compilers.

OpenCOBOL translates COBOL into C and compiles the translated code using the native C compiler. You can build your COBOL programs on various platforms, including Unix/Linux, Mac OS X, and Microsoft Windows. cobc binaries exist for HP/UX, zOS, SPARC, RS6000, AS/400 and more.

The compiler is licensed under GNU General Public License.
The run-time library is licensed under GNU Lesser General Public License.
