Description: 这里以开始定义的PASCAL语言子集的源程序作为词法分析程序的输入数据。在词法分析中，自文 件头开始扫描源程序字符，一旦发现符合“单词”定义的源程序字符串时，将它翻译成固定长度的单 词内部表示，并查填适当的信息表。经过词法分析后，源程序字符串（源程序的外部表示）被翻译成 具有等长信息的单词串（源程序的内部表示），并产生两个表格：常数表和标识符表，它们分别包含 了源程序中的所有常数和所有标识符。- Here starts the PASCAL language subset source program which
defines to take the lexical analyaer the data-in. In the lexical
analysis, starts from the article article to scan the source program
character, once discovered when conforms to "the word" the definition
source program character string, translates it the fixed length the
word interior to indicate, and looks up fills in the suitable
information table. After the lexical analysis, the source program
character string (source program exterior expression) is translated
has and so on the long information the word string (source program
internal expression), and produces two forms: The chart and the
identifier table, they have separately contained in source program all
constants and all identifiers.

Description: 一、 实验内容
S语言的编译程序的词法分析部分实现
从左到右扫描每行S语言源程序的符号，拼成单词，换成内部表示（token）
二、 实验要求
要求实现编译器的以下功能：
组织源程序的输入
按规则拼写单词，并转换成二元形式
删除空格及无用符号（如回车符，字符常数的引号符等）
发现并定位错误
建立单词表、符号表、常数表等文件
三、 实现方法
数据结构
1、 输入
S语言源程序，为文本文件
2、 输出
词法分析程序的运行结果是：产生一个单词序列文件（token文件）和一个常数表、一个符号表文件，并输出错误信息。
（1） token文件结构
token文件用于存放从S语言源程序中扫描出来的一个个单词符号的机内表示，其文件结构如下：
typedef struct token
{
nt label
char name[30]
int code
int addr
}token
说明：
label：单词序号；
name[30]：单词本身；
code：单词的编辑；
addr：地址，单词本身保留字时值为-1，为标识符成常数时为大于0常数，即该标识符成常数在符号表中的入口地址。
-one, Experiment S language compiler of lexical analysis to achieve whatever S scanning each line of source language symbols, makes up words, replaced internal said (token) 2, the experimental requirements call for compiler of the following functions :

Description: 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.)
