Have you ever followed instructions for knitting something or have you read a piece of music? If you have, you have behaved in a similar way to a computer. A computer obeys a program to carry out a particular task. Just as a knitting pattern is expressed in numbers and piece of music in lines and dots, so a computer program is expressed in the form of programming language. Like the English language (or any other language), there are rules of grammar, and a program must be correct in every way.
There are hundreds of programming language, but only a few are well-known and widely used. The most popular language which is used in offices is called Cobol. This language is used for printing payrolls and keeping records of goods. Engineers and scientists use Fortran in order to carry out calculations. However neither of these two programs is very popular with people working on home computers. Basis is the most popular language for home computers, chiefly because it is easy to learn and use.
Although these languages are useful for many purposes, it is time that a new simple program was devised. Such a program ought to be not only easy to use but also completely reliable.
