| ABC 1. An language and programming environment from , Netherlands. It is interactive, structured, high-level, and easy to learn and use. It is a general-purpose language which you might use instead of , or . It is not a systems-programming language but is good for teaching or prototyping. ABC has only five data types that can easily be combined; , yet without declarations; data limited only by memory; refinements to support top-down programming; nesting by indentation. Programs are typically around a quarter the size of the equivalent or program, and more readable. ABC includes a programming environment with editing, s, s and multiple workspaces and arithmetic.
