NAR 2 - Standard Assembly Language Syntax

Standard Assembly Language Syntax

NAR 2 assembly language syntax was straightforward and easy to parse. Each program line could contain up to one instruction specified as follows:

  1. Instruction mnemonic
  2. Whitespace, if instruction specifies any index registers, addressing mode or a parameter and then comma-separated:
    1. Name of index register, if used
    2. Names of addressing mode flags (also comma separated)
    3. Parameter value

Sample code:

aum X1, p, 0 mua n, 1 aum 15 pir X1, p, n, 1 mua X1, p, n, 0 oduf n, 1 oduf X2, p, n, 0

Famous quotes containing the words standard, assembly and/or language:

    “Error is a supposition that pleasure and pain, that intelligence, substance, life, are existent in matter. Error is neither Mind nor one of Mind’s faculties. Error is the contradiction of Truth. Error is a belief without understanding. Error is unreal because untrue. It is that which seemeth to be and is not. If error were true, its truth would be error, and we should have a self-evident absurdity—namely, erroneous truth. Thus we should continue to lose the standard of Truth.”
    —Mary Baker Eddy (1821–1910)

    “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)

    “The writer’s language is to some degree the product of his own action; he is both the historian and the agent of his own language.”
    —Paul De Man (1919–1983)
