Line 39: You may from time to time hear of operating systems written in languages which are usually interpreted, or which used an interpreter of some sort: JavaOS, [http://en.wikipedia.org/wiki/Genera_%28operating_system%29 Genera] (the Symbolics Lisp Machine OS), Smalltalk-80, UCSD Pascal, the various FORTH systems, etc. Most of these fall into one of three categories : * The operating system runs in a low-level interpreter, written in Assembly or some systems language like C, which is what actually interacts with the hardware. In effect, the 'operating system' is just an application running on top of another, lower-level OS. Smalltalk-80, UCSD Pascal, and ~~JavaOS~~some Java OSes work like this, though they also have some modules which are compiled to native code as well (see below). * All or part of the code has been compiled to native code. This may involve using a sub-set of the language with reduced runtime requirements (e.g., [http://www.citeulike.org/user/hamish/article/201596 pre Scheme], or [http://www.squeak.org/features/vm.html Slang] - while they have not been used for OS development to date, they do demonstrate this sort of low-level implementation language which can be used this way).
