Unformatted text preview: tands for Beginners All-purpose Symbolic Instruction Code. It was developed in the year 1964 by Professor John Kemeny and Thomas Kurtz at Darmouth College in the United States. Their main objectives for developing a new programming language were as follows: 1. It should be an interactive language that permits direct communication between the user and the computer during the preparation and use of programs. 2. It must be easy for non2science students to learn and use the language. In order to meet these objectives, the designers took the following approach in the design of BASIC language: 1. It was designed to use terminals as the method of computer access. Before this, most programs were entered into computers through either punched cards or paper tape. 2. It was designed as an interpreted language (unlike FORTRAN and COBOL which were compiled languages) so that programmers could create, run, test and debug a program in interactive mode. 3. It was designed with very few statements and grammatical rules so that it could be easily learnt and used by beginner programmers. The language translator used for BASIC is an interpreter instead of a compiler. This allows a programmer to check for syntax errors and immediately correct it as the program is entered. It also makes the language simple and easy to implement and use. Because of its simplicity to implement, learn and use, BASIC was the first highlevel language to be implemented on personal computers when they were introduced. Today, BASIC is available in almost all personal computers and even in some pocket calculators. This fact makes it one of the most widely installed computer languages in the world. Though simple and easy to learn, BASIC is quite flexible and reasonably powerful. It can be used for both business and scientific applications. Users of BASIC range from school students to scientists and engineers to business managers. It is also used to teach programming basics to beginners. A minimal version of BASIC was standardized by ANSI in 1978. But this standard is so simple that it has been...
