该程序可将逆波兰表达式转换为C语言程序。-the inverse process can be converted to Poland expression C language program.

JC1.0。本编译器包含完整的文档与程序。借助 Lex & Bison, masm 开发。语句5个，支持混合运算。输入输出作为两个 IO 语句（函数调用），由汇编实现并编译为 io.obj，将由 Link 链接。生成 EXE。整个流程完整清晰，代码易读。-JC1.0. The compiler includes complete documentation and procedures. With Lex Bison, can develop. Statement 5, support mixed computing. Input and output as two IO statement (function call), compiled by the compiler to achieve and io.obj will link Link. EXE generation. The entire process, complete and clear, legible code.

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.
