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:

    Had every Athenian citizen been a Socrates, every Athenian assembly would still have been a mob.
    James Madison (1751–1836)

    Perspective, as its inventor remarked, is a beautiful thing. What horrors of damp huts, where human beings languish, may not become picturesque through aerial distance! What hymning of cancerous vices may we not languish over as sublimest art in the safe remoteness of a strange language and artificial phrase! Yet we keep a repugnance to rheumatism and other painful effects when presented in our personal experience.
    George Eliot [Mary Ann (or Marian)

    It is thus tolerance that is the source of peace, and intolerance that is the source of disorder and squabbling.
    Pierre Bayle (1647–1706)

    ... 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–?)
