Common business oriented, language or cobol language example , was released in 1960. The U. S. department of defense, which is one of the world’s largest buyers of data processing equipment on longer wanted to commission the development of software on unalterable assembly language.
So it funded the development of this programming language for business. The leader of the team that developed COB0L was naval officer grace hopper. The concern over three differences among versions of FORTRAN -all machine dependent led the developed COBOL to adopt machine independence as one of the primary objectives. The U. S. government then adopted a policy that required a computer to have the COBOL programming language available if the vendor wanted to sell or lease the equipment to the government. The latest ANSI standards for COBOL were released in 1985.
The commands and syntax of COBOL’s instruction statements resemble sentences you would use when speaking English, Spanish, French, or German, for example. As a result, it is sometimes easier for a programmer to read and understand COBOL than FORTRAN. COBOL is used primarily on minicomputers and mainframes but is also available for microcomputer use and it is the language mist used for business applications.
Some advantage of COBOL
> It is machine independent.
> It is English-like statements are easy to understand.
> It can handle many files records and fields.
> It is easily handles input and output operations.
Some disadvantages of COBOL
Because it is so readable, it is wordy; thus even simple programs are lengthy, and programmer productivity is slowed. It cannot handle mathematical processing as well as FORTRAN, BASIS, or C.
In spite of the drawbacks, many programmers believe that COBOL will remain the most widely used language for writing business applications. Many companies are using applications written in COBOL that represent a huge investment that business community is not yet prepared to throw away.
