    return "@SP\n" +
            "AM=M-1\n" +
            "D=M\n" +
            "A=A-1\n" +
            "D=M-D\n" +
            "@FALSE" + arthJumpFlag + "\n" +
            "D;" + type + "\n" +
            "@SP\n" +
            "A=M-1\n" +
            "M=-1\n" +
            "@CONTINUE" + arthJumpFlag + "\n" +
            "0;JMP\n" +
            "(FALSE" + arthJumpFlag + ")\n" +
            "@SP\n" +
            "A=M-1\n" +
            "M=0\n" +
            "(CONTINUE" + arthJumpFlag + ")\n";
