151 - Introduction to Cobol Programming
History
COBOL (Common Business Oriented Language)
was one of the earliest high-level programming languages. It was
developed in 1959 by a group of computer professionals called the
Conference on Data Systems Languages (CODASYL). Since 1959 it has
undergone several modifications and improvements. In an attempt
to overcome the problem of incompatibility between different
versions of COBOL, the American National Standards Institute (ANSI)
developed a standard form of the language in 1968. This version
was known as American National Standard (ANS) COBOL. In 1974,
ANSI published a revised version of (ANS) COBOL, containing a
number of features that were not in the 1968 version. In 1985,
ANSI published still another revised version that had new
features not in the 1974 standard. The language continues to
evolve today. Object-oriented COBOL is a subset of COBOL 97,
which is the fourth edition in the continuing evolution of ANSI/ISO
standard COBOL. COBOL 97 includes conventional improvements as
well as object-oriented features. Like the C++ programming
language, object-oriented COBOL compilers are available even as
the language moves toward standardization.
