C64-FORTH is a fourth-generation programming language that in many respects is very different from other lanquages. In relation to its size, its power is unequalled. In just 8K, a typical minicomputer FORTH version supplies structured, compact and extremely fast code, virtual memory, a resident macro assembler and a resident editor, as well as multitasking capability. FORTH is even able to extend itself and its compiler. It is a metalanguage.
