GnuCOBOL (formerly OpenCOBOL) is a free COBOL compiler. cobc translates COBOL to executable using intermediate C sources, providing full access to nearly all C libraries.
OpenCOBOL 1.1 continued on as GNU Cobol 1.1. Officially posted to ftp://ftp.gnu.org/gnu/gnucobol, also available here.
GnuCOBOL 2.0 is on its way to a pre-release.
A superb manual by Gary Cutler, along with a FAQ / How-To, and other documentation is indexed at http://opencobol.add1tocobol.com/guides

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.
A well-written compiler for a very underrated if long-in-the-tooth language. A fine support community.
This is what COBOL needs.. A new system not requiring a main frame. COBOL needs to be ported to the PC environment. This gives access to COBOL on a lower budget.
In many cases the GNU Cobol will become a valid replacement for proprietary (and thus expensive) software development platforms (got much experience with other UNIX, VMS and Mainframe based products). It has got a high priority for me, and my new software development projects are being considered to be managed with GNU Cobol.
Easy to use, with great support!
