利用字符二维数组对文法、First集、Follow集、终结符集、非终结符集等数据进行存储，还有一个是状态表存储DFA的状态。二维TAB表对其中的DFA表进行存储，横坐标是状态号，纵坐标为文法中的符号（终结符和非终结符）。-Two-dimensional array of characters to use grammar, First Set, Follow sets, at the end of sets, sets and other non-terminator data storage, there is a state table is stored DFA state. Two-dimensional table TAB which DFA table storage, the abscissa is the state number, longitudinal coordinates for the grammar of the symbols (and non-terminator terminator).
