Description:	ABC is an imperative language embedded in its own environment. It is interactive, structured, high-level, very easy to learn, and easy to use. It is suitable for general everyday programming, such as you would use BASIC, Pascal, or AWK for. It is not a systems-programming language. It is an excellent teaching language, and because it is interactive, excellent for prototyping. ABC programs are typically very compact, around a quarter to a fifth the size of the equivalent Pascal or C program. However, this is not at the cost of readability, on the contrary in fact.
