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:
“It is easier to move rivers and mountains than to change a person’s basic nature.”
—Chinese proverb.
“A healthy soul stands united with the Just and the True, as the magnet arranges itself with the pole, so that he stands to all beholders like a transparent object betwixt them and the sun, and whoso journeys towards the sun, journeys towards that person. He is thus the medium of the highest influence to all who are not on the same level.”
—Ralph Waldo Emerson (1803–1882)
“Society cannot share a common communication system so long as it is split into warring factions.”
—Bertolt Brecht (1898–1956)
