nature: procedural language

history: COBOL (COmmon Business Oriented Language) was created in May 1959 by the Short Range Committee of the U.S. Department of Defense (DoD) for business programming. The CODASYL committee (COnference on DAta SYstems Languages) worked from May 1959 to April 1960. Official ANSI standards included COBOL-68 (1968), COBOL-74 (1974), COBOL-85 (1985), and COBOL-2002 (2002). COBOL 97 (1997) introduced an object oriented version of COBOL. COBOL programs are divided into four divisions: identification, environment, data, and procedure. The divisions are further divided into sections. Introduced the RECORD data structure. Emphasized a verbose style intended to make it easy for business managers to read programs. Admiral Grace Hopper is recognized as the major contributor to the original COBOl language and as the inventor of compilers.

ANSI version of COBOL defined in 1968.
