Forth
{{language|Forth |gc=no |untyped=yes |LCT=yes}} {{language programming paradigm|concatenative}} {{language programming paradigm|imperative}} '''Forth''', a [[procedural programming|procedural]], [[stack]]-oriented and [[reflective programming]] language without type checking, Forth features both interactive execution of commands (making it suitable as a shell for systems that lack a more formal [[:Category:Operating_Systems|operating system]]) and the ability to compile sequences of commands for later execution. Some Forth versions (especially early ones) compile threaded code, but many implementations today generate optimized machine code like other language compilers.
Where not otherwise specified, examples conform to the 1994 [[ANSI]] Standard, also known as '''ANS Forth'''. Most Forth implementations now conform to this standard, often with system-specific extensions and convenience libraries. Some examples use words that are not in the standard, but which have become accepted as [[Forth common practice|common practice]] since 1994. Standard words should be uppercase, but most Forth systems are case-insensitive.
