COBOL (/ˈkoʊbɒl, -bɔːl/; Common Business Ofented Language iborasidan qisqartirilgan; tarjimasi „umumqabul qilingan amaliy til“) — EHM yordamida iqtisodiy-hisob va boshqarish masalalarini yechish dasturini bayon qilishda qoʻllaniladigan dasturlash tili. Algoritmlarni EHMning qandayligiga bogʻliq boʻlmagan shakldagi yaqqol va ixcham qaydi olinishini taʼminlaydi. 1960-yillarda AQShda ishlab chiqilgan. Tilning inglizcha va ruscha variantlari mavjud; shakli matn koʻrinishda boʻladi. COBOL katta hajmdagi axborotlarni kiritish va chiqarish, razryadi oʻzgaruvchan sonlar ustida ishlash, chiqadigan axborotlarni murakkab hisobot shakli koʻrinishida tahlil qilish uchun ishlov beradi. COBOL algolta nisbatan amaliy operatsiyalarning odatdagi tiliga yaqin. COBOLda tuziladigan katta dasturlarni qisqartirish va ularni joylash uchun maxsus vosita bor^[8].

"The Short-Range Committee worked diligently from June 1959 on, but there were great difficulties in having a fairly large committee try to create a programming language. In November, the Short-Range Committee chair appointed six people to develop specifications for consideration: William Selden and Gertrude Tierney (IBM), Howard Bromberg and Norman Discount (RCA), and Vernon Reeves and Jean E. Sammet (Sylvania Electric Products). We worked for two full weeks (including some round-the-clock sessions) in November 1959 and sent the proposed specifications to the full Short-Range Committee, which accepted almost all of them. After some editing (by the same six people), we turned in the specifications as a final report in December to the Executive Committee, which accepted them in January 1960. After some further editing, the Government Printing Office issued Cobol 60.

Thus, while her indirect influence was very important, regrettably the frequent repeated statements that "Grace Hopper developed Cobol" or "Grace Hopper was a codeveloper of Cobol" or "Grace Hopper is the mother of Cobol" are just not correct."
