        !            13: points to an area of core whose length (in bytes) is given by
        !            14: bufsiz______.
        !            15: After this call, the user's program counter (pc)
        !            16: is examined each clock tick (60th second);
        !            17: offset______ is subtracted from it, and the result multiplied by
        !            18: scale_____.
        !            19: If the resulting number corresponds to a word
        !            20: inside buff____, that word is incremented.
        !            21: .s3
        !            22: The scale is interpreted as an unsigned,

        !            25: in buff____; 77777(8) maps each pair of instruction words
        !            26: together.
        !            27: 2(8) maps all instructions onto the beginning of

        !            30: Profiling is turned off by giving a scale_____ of 0 or 1.
