Cpress 68013A is the best one -Cypress 68013a appliaction example

另一版本的词法分析器- Another edition morphology analyzer

lcd的初始化等-lcd initialization, etc.

我的词法分析程序,是编译原理要做的一个，放上来大家-my lexical analysis procedure to be done is to compile a principle, we see Fangshanglai

PL/0语言可以看成PASCAL语言的子集，它的编译程序是一个编译解释执行系统。PL/0的目标程序为假想栈式计算机的汇编语言，与具体计算机无关。-PLO

基于pascal的词法分析程序-based on the lexical analysis procedure

词法分析器 对输入的程序进行分析，将关键字，保留字与系统标识符分开，并对其属性进行说明。 建立数组，将单词读入，对单词的ASCII码进行判断，将在ASCII码值在一定区间进行区分（使用if语句来判断），分开来后，对其所在ASCII值区间的不同，给予以不同的属性(比如：系统保留字…），词法分析器完成后要能识别+,-,=等字符。-lexical analyzer on the importation procedures for analysis, keyword, the word reservation system with separate identifier, and a description of their attributes. The establishment of an array, you read the word, the right word ASCII judgment, in ASCII value in a certain area and distinguish between (use to determine if statements), separately, its value lies ASCII range of different, to give a different properties (such as : system retain the word ...), after the completion of a lexical analyzer to identify,-, =, etc. characters.

语法分析器，对已给pascal语言文法，构造LL(1)分析表，编制语法分析程序，要求将错误信息输出到语法错误文件中，并输出分析句子的过程-Parser that have been to the pascal language grammar, structure LL (1) analysis table, the preparation of parsing procedure that requires the output to the error message syntax error file, and output analysis of the process of sentence

我重新上传了我的这个(（x+x）+……）词法分析程序。去掉了编译后的debug/release目录-I re-uploaded my ((x+ X)+ ... ...) Lexical analysis program. Removed after compiling debug/release directory

打开2.tab.c编译运行，a.txt为测试用的PL/0程序。 2.output中有所有的产生式和LALR分析表的所有状态。- Opens the 2.tab.c translation movement, a.txt is measures the test the PL/0 procedure. In 2.output has all production patterns and LALR analytical table all conditions.
