说明：  三、 实验要求 1. 使用 PL/0 语言编写程序，实现输出斐波那契数列前 20 项数值。 2. 从 PL/0 编译程序源码中抽出词法分析部分，构建 PL/0 独立词法分析程序。功能：输入为 PL/0 源程序， 输出为单词符号的序列；对于标识符和无符号整数，显示单词种别和单词自身的值两项内容；对于其他单词符 号，仅显示其单词种别。 3. 使用 AutoFlowchart 画出独立词法分析程序的程序流程图，并分析每部分的功能和特点。(Iii. Experimental requirements 1. Use PL/0 language to write programs to output the first 20 values of Fibonacci sequence. 2. Extract the part of lexical analysis from PL/0 compiler source code, and build PL/0 independent lexical analysis program. Function: Input as PL/0 source program, Output a sequence of word symbols; For identifiers and unsigned integers, the word class and the value of the word itself are displayed. For other word characters , showing only its word class. 3. Use AutoFlowchart to draw the program flow chart of the independent lexical analysis program and analyze the functions and characteristics of each part.)

说明：  光栏法的基本思想是（图1）：定义一个扇形区域，通过判断曲线上的点在扇形外还是在扇形内，确定保留还是舍去。(The basic idea of ​ ​ light field is (Figure 1): definition of a fan-shaped region, by determining the point on the curve outside the sector or sector, to identify the retained or discarded.)

AWARD BIOS源代码,支持的CHIPSET请看文件,有同型号的板子烧上去就可以跑-the compressed file contains the source code of AWARD BIOS type D1E.Supported chipsets are listed in the related file.One can complie,download and run it on the mainboard if he has such one.
