Cobol profile In this paper I pursue the goal to create a short profile for the programming language COBOL, I am going to tell about languages main applications to show the Metalanguage applied, to illustrate syntactic elements of this programming language. COBOL (COmmon Business Oriented Language) is a high-level language of programming created by the CODASYL Committee (Conference on Data Systems Languages) in 1960. COBOL is developed for business, normally file-oriented, applications. It is not created for systems programs writing. For example you cant create a compiler or an operating system with the help of COBOL. COBOL applications are very large.
Many COBOL applications include more than 1, 000, 000 lines of code - with 6, 000, 000 + line applications. COBOL applications are also very durable Business applications for 10 - 30 years-old are common. COBOL usually works huge volume of data. COBOL is an easy with a narrow range of function.
It supports a simple uncomplicated programming approach. Notwithstanding that its application are rather limited, COBOL is a well matched to its main problem domain. It is simple to work with for programmers which didnt get used to the business programming paradigm, where simple rules of programming are very important. The standard of the language COBOL does not belong to any exacting machine. COBOL can be used to any hardware platform - from any Windows, to Unix, AS/ 400, VSE, OS/ 2, DOS, VMS, Unisys, DG, VM, and MVS. COBOL programs are a bit pleonastic particularly when they are compared to other languages like C.
COBOL syntax is distinct applying exacting data called the COBOL MetaLanguage. To abridge the syntax diagrams and cut the number of regulations that must be clarified, individual operand endings are sometimes used These are the meanings of them: $i
uses an alphanumeric data-item
$il
uses an alphanumeric data-item or a string literal
#i
uses a numeric data-item
#il
uses a numeric data-item or numeric literal
$#i
uses a numeric or an alphanumeric data-item COBOL programs have hierarchical structure. Each part of the hierarchy includes one or more elements. The program consists of Divisions, Sections, Paragraphs, Sentences and Statements. A Division may include one or more Sections, a Section one or more Paragraphs, a Paragraph one or more Sentences and a Sentence one or more Statements. The structure of Cobols program can be represented as follows: Bibliography Ankrum, T.
