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:
“Our assembly being now formed not by ourselves but by the goodwill and sprightly imagination of our readers, we have nothing to do but to draw up the curtain ... and to discover our chief personage on the stage.”
—Sarah Fielding (17101768)
“These are our grievances which we have thus laid before his majesty with that freedom of language and sentiment which becomes a free people, claiming their rights as derived from the laws of nature, and not as the gift of their chief magistrate.”
—Thomas Jefferson (17431826)
“Might not the beatific vision become a source of boredom, in the long run?”
—Samuel Beckett (19061989)
“Faultless honesty is a sine qua non of business life. Not alone the honesty according to the moral code and the Bible. When I speak of honesty I refer to the small, hidden, evasive meannesses of our natures. I speak of the honesty of ourselves to ourselves.”
—Alice Foote MacDougall (18671945)
