A new language, in the year 1959 named COBOL (Common Business Oriented Language) was introduced remembering the business purpose applications.
The board of directorate which is referred as CODASYL (i.e., Conference on the DATA System Language) COBOL programming language committee recognized a COBOL maintenance committee to remain COBOL in step during times. The first COBOL compiler became exist in the year1962. The later version with several latest additions was published in the year 1965. In August 1968 a standard version of the language was approved by the American National Standard Institute (i.e., ANSI). This standard version was again customized in 1974 and is termed as ANSI-74 COBOL or COBOL -74. The revision procedure has been constant and in the year 1985 a modified standard was introduced. This standard was referred as COBOL-85.
Structure of a COBOL Program:
Every COBOL program should have the 4 divisions in the order in which they are specified below:
1. Identification division
2. Environment Division
3. Data Division
4. Procedure Division
2. Environment Division
3. Data Division
4. Procedure Division
In the Identification division the particulars about the author, date of writing the program etc will be specified.
In the atmosphere division, the particulars around the computer surroundings under which the program was compiled and written etc. will be knowledgeable.
In Data division, the variables that are utilized by the program will be stated and it is a significant division for the program.
In procedure division, the programming statements will be written and it is the most essential division.
In procedure division, the programming statements will be written and it is the most essential division.
Beneath the divisions there are various sections intended for specific purposes. To name a little, the working-storage section and File section come beneath the Data division. Their goal will be to allocate memory space for the variables and to inform the files that are to be utilized with the program.
The statement of COBOL program might be written in one or more coding lines. To carry on in the subsequent line one has to use the hyphen (-) in the column 7.
In COBOL there are numerous options to get help from experts, students are assisting with Programming Assignment Help and there are many COBOL experts who are offering assignment help online you can choose your tutor as per your necessitate.
