GCC now includes an ISO COBOL compiler, gcobol. It has been tested on x86-64 and AArch64 targets. It is not expected to work on 32-bit systems. Efforts are underway to adapt it to other machine architectures that support native 128-bit computation.
gcobol passes much of the NIST CCVS/85 test suite (except for parts that are now obsolete). It uses ISO/IEC 1989:2023 as a reference specification. Some parts of that document, notably object-orientation features, are yet to be implemented. Beyond ISO, gcobol recognizes some syntax common on other compilers, with special attention given to IBM.
