In computer programming, the basic object system (BOS) is a C-callable library that implements the notion of object and which uses tcl as its interpreter for interpreted methods (you can have "compiled" methods in C, and mix compiled and interpreted methods in the same object, plus lots more). You can subclass and mix in existing objects using BOS to extend, among other things, the set of tk widgets. BOS is a class-free object system, also called a prototype-based object system; it is modelled loosely on the Self system from Stanford University.

Famous quotes containing the words basic, object and/or system:
“Insecurity, commonly regarded as a weakness in normal people, is the basic tool of the actor’s trade.”
—Miranda Richardson (b. 1958)

“I candidly confess that I have ever looked on Cuba as the most interesting addition which could ever be made to our system of States. The control which, with Florida, this island would give us over the Gulf of Mexico, and the countries and isthmus bordering on it, as well as all those whose waters flow into it, would fill up the measure of our political well-being.”
—Thomas Jefferson (1743–1826)
