Example of a selection of instructions (for a virtual computer) with the corresponding address in memory where each instruction will be placed. These addresses are not static, see memory management. Accompanying each instruction is the generated (by the assembler) object code that coincides with the virtual computer's architecture (or ISA).

Famous quotes containing the words assembly, language, source and/or code:
“That man is to be pitied who cannot enjoy social intercourse without eating and drinking. The lowest orders, it is true, cannot imagine a cheerful assembly without the attractions of the table, and this reflection alone should induce all who aim at intellectual culture to endeavor to avoid placing the choicest phases of social life on such a basis.”
—Mrs. H. O. Ward (1824–1899)
“Man, even man debased by the neocapitalism and pseudosocialism of our time, is a marvelous being because he sometimes speaks. Language is the mark, the sign, not of his fall but of his original innocence. Through the Word we may regain the lost kingdom and recover powers we possessed in the far-distant past.”
—Octavio Paz (b. 1914)
“We are threatened with suffering from three directions: from our own body, which is doomed to decay and dissolution and which cannot even do without pain and anxiety as warning signals; from the external world, which may rage against us with overwhelming and merciless forces of destruction; and finally from our relations to other men. The suffering which comes from this last source is perhaps more painful than any other.”
—Sigmund Freud (1856–1939)
“... the self respect of individuals ought to make them demand of their leaders conformity with an agreed-upon code of ethics and moral conduct.”
—Mary Barnett Gilson (1877–?)
