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:
“Good shot, bad luck and hell are the five basic words to be used in a game of tennis, though these, of course, can be slightly amplified.”
—Virginia Graham (b. 1912)
“Perchance the time will come when every house even will have not only its sleeping-rooms, and dining-room, and talking-room or parlor, but its thinking-room also, and the architects will put it into their plans. Let it be furnished and ornamented with whatever conduces to serious and creative thought. I should not object to the holy water, or any other simple symbol, if it were consecrated by the imagination of the worshipers.”
—Henry David Thoreau (1817–1862)
“The system was breaking down. The one who had wandered alone past so many happenings and events began to feel, backing up along the primal vein that led to his center, the beginning of hiccup that would, if left to gather, explode the center to the extremities of life, the suburbs through which one makes one’s way to where the country is.”
—John Ashbery (b. 1927)
