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