FORTH
FORTH A programming language formerly much in vogue among users of microcomputers. FORTH operands are held on a stack, and programs take the form of strings in reverse Polish notation. A vital feature of FORTH is that a symbol (a WORD) can be associated with any program string, and such a user-defined word can then be used in expressions on equal terms with the system words (operators). This makes FORTH a flexible extensible language in which it is possible to define a customized language for, say, the control of a scientific instrument. The FORTH system is very compact; the interpreter and the dictionary containing the system-defined words can be fitted into 8K bytes. FORTH is now little used, but the same principles are found in PostScript.
