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. Official releases at ftp://ftp.gnu.org/gnu/gnucobol
GnuCOBOL 2.0 is on its way to pre-release. All versions, old and new, hosted here.
A programmer's guide, by Gary Cutler, and other documentation is indexed at http://opencobol.add1tocobol.com/guides
OpenCOBOL was written by Keisuke Nishida and Roger While, from 2001 to 2012.
GnuCOBOL is also authored by Simon Sobisch, Sergey Kashyrin, and Ron Norman.

Great compiler for every job production and test. perfect
This GNU Cobol is an exercise in frustration for the Windows user that don't like to use Linux. You either have to use CYGWin and then it will give you an error message when you try to compile something as easy as Hello World. This is utterly ridiculous in the ease of the software.
Good alternative to commercial cobol compilers.
Really powerful !
Wow, such a fantastic product! I don't know how commercial COBOL solutions can even think they can stay in business with their archaic licensing fees! I ported our product from a commercial compiler platform in less than 30 minutes and it's working flawlessly under GnuCOBOL. You owe it to yourself to check this product out. It does not disappoint.
