COBOL - programming language.

COBOL, COmmon Business Oriented

Language)-one of the oldest programming

languages (the first version was released in

1959), designed primarily for the

development of business applications.

The project Manager for the creation of

COBOL was Grace Hopper. Almost since its

inception the COBOL is an ANSI-

-standardized programming language.

Object-oriented programming tools and

other modern language constructs have

been added to the 2002 language

standard in COBOl.

COBOL is usually criticized for verbosity and

cumbersome, because one of the goals of

the creators of the language was to bring

the design as close as possible to the

English language ), so it is widely known the

statement of Edsger W. Dijkstra "the use of

COBOL cripples the mind. His teaching,

therefore, must be regarded as a criminal

offense."

At the same time, COBOL had excellent tools

for its time to work with data structures and

files, became the first language in which the

data type "record" appeared, it provided him

with a long life in business applications, at

least in the United States.

By 1997, about 240 billion lines of code in

COBOL were actively used, about 90% of

financial transactions in the world and 75%

of commercial transactions were

processed by code in COBOL, the total

cost of the code used is 2 trillion dollars.
