* '''COBOL
* '''COBOL-65''' added some new features to the original specification.

* '''COBOL 2002''' is the current version of COBOL and was published by [[ISO]] as ISO/IEC 1989. It included a host of new features, most notably including object-oriented programming. However, there were also other features, including: floating-point support, portable arithmetic results, pointers, calling conventions to other languages, function prototypes, [[XML]] facilities and support for execution within framework environments. This standard has suffered from poor vendor support, due to little commercial demand for the new features.<ref>John Billman & Huib Klink, 'Thoughts on the Future of COBOL Standardization', [https://www.cobolstandard.info/j4/files/08-0034.pdf]</ref>▼
* '''X/Open COBOL''' was a technical standard published by the X/Open Group in 1991 to facilitate uniformity of implementations and program portability. Based on COBOL-85, it excluded much of its optional modules and obsolete features, and also specified some common non-ANSI extensions that would later become incorporated into the standard, such as the screen section for TUI programming, and record locking.<ref>{{Cite book|author=X/Open|title=Technical Standard: COBOL Language|url=https://pubs.opengroup.org/onlinepubs/009680799/toc.pdf}}</ref>
* '''COBOL 2014''' is the latest version of the standard, published on July 8th, 2014 and accepted by [[ISO]] early that summer, and then adopted by [[ANSI]] on Oct 31st, 2014. <ref>ISO/IEC 1989:2014 Information technology – Programming languages, their environments and system software interfaces – Programming language COBOL', [https://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=51416]</ref> It includes numeric definitions following the [[IEEE]] 754 standard.▼
▲* '''COBOL 2002'''
▲* '''COBOL 2014'''
* '''COBOL 2023''' is the latest version of the standard, adopted in January 2023. It includes the standardizations of many previously nonstandard extensions, including transaction processing, asynchronous messaging, line sequential file organization, enhanced string manipulation, boolean shifting operators and a sleep statement.
