FORTH implements a language that gives the user the complete access to hardware capabilities, and complete freedom to design a compact POL. Interestingly enough, FORTH applications do not use subscripts, counters and such house-keeping variables. They require very little data storage - usually in the form of arrays. They are composed mostly of definitions - seemingly endless nests of definitions - which are simple to write and simple to use. FORTH applications make efficient use of computer resources, and share these readily with other applications. In a word, FORTH is THE computer language.
