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 2.2 is on release candidate.
A programmer's guide, by Gary Cutler, and other documentation, is indexed at
OpenCOBOL was written by Keisuke Nishida and Roger While, from 2001 to 2012.

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.
