COBOL est un langage de programmation créé en 1959 et il signifie : Common Business Oriented Language et à été créé principalement pour développer des applications de gestions utilisant des fichiers pour les mainframes IBM. Le langage COBOL était de loin le langage le plus employé des années 1960 à 1980.
D'après une enquête de Micro Focus, cette années seulement 18% des personnes interrogées avaient déjà entendu parler de COBOL. Pourtant, il existe plus de 200 milliards de lignes de code COBOL qui ont étés écrites, et de nombreuses autres sont créés chaque jour.
Selon Mike Gilpin, analyste chez Forrester Research : 32% des entreprises utilisent encore COBOL pour le développement ou la maintenance. "COBOL est l'une des rares langues écrites au cours des 50 dernières années, c'est lisible et compréhensible, dit-il. "Langages de programmation modernes sont ridiculement difficile à comprendre."
Un exemple de programmation Hello World en COBOL :
|Code :||Sélectionner tout|
IDENTIFICATION DIVISION. PROGRAM-ID. HELLO-WORLD. PROCEDURE DIVISION. DISPLAY 'Hello, world'. STOP RUN.

World’s most pervasive computer language first named 50 years ago
Help celebrate COBOL’s 50th birthday at www.cobol.com
NEWBURY, England, 18 September 2009 - Micro Focus® (LSE.MCRO.L), a leading provider of enterprise application management, testing and modernisation solutions, today celebrates fifty years since the name COBOL was given to the computer language which continues to underpin the modern world.
The name COBOL (COmmon Business-Oriented Language) was agreed during a meeting of the Short Range Committee, the organisation responsbile for submitting the first version of the langauge, 18th September 1959. This followed a meeting at the Pentagon where guidelines for COBOL were first laid down.
Despite its age, COBOL still plays a pivotal role in running most of the world’s businesses and public services, from powering almost all global ATM transactions, running nearly three quarters of the world’s business applications, and booking hundreds of holidays every single day. There is understood to be over 200 billion lines of COBOL code in existence, with hundreds more being created every single day.
In May this year, Micro Focus published research which showed that people still use COBOL at least ten times throughout the course of an average working day. Yet, despite using the technology so often, only 18% of those surveyed had ever actually heard of COBOL. Equivalent research conducted by Micro Focus in the US showed Americans rely on COBOL even more, using it at least 13 times per day.
Stuart McGill, CTO, Micro Focus says “COBOL can trace its origins to the very start of the computer age, yet its applications continue to deliver to businesses and the public sector every single day. In an industry constantly driven by innovation and the ‘next big thing’, it is a real testament to the language’s resilience, flexibilty and relevance to the task at hand that it is still so widely used today. Customers come to us to modernise their business critical applications – not rip them out – because they hold deep business intelligence and continue to deliver value every single day. The vast majority of these applications have been written in mature languages, such as COBOL. Very few languages could make the same claim fifty years on,” concludes McGill.
Mike Gilpin, analyst at Forrester research and former COBOL programmer states, “…32% of enterprises say they still use COBOL for development or maintenance… COBOL is one of the few languages written in the last 50 years that's readable and understandable… Modern programming languages are ridiculously hard to understand."
