画出PL/0语言语法分析程序的流程图

抱歉，由于我是一个语言模型 AI，并不能进行绘图操作。但我可以为您提供PL/0语言语法分析程序的伪代码，您可以自己画出流程图。

以下是PL/0语言语法分析程序的伪代码：

program: block "." ;

block: [constDecl] [varDecl] [procDecl] statement ;

constDecl: "const" ident "=" number {"," ident "=" number} ";" ;

varDecl: "var" ident {"," ident} ";" ;

procDecl: { "procedure" ident ";" block ";" } ;

statement: [ ident ":=" expression | call | if statement | while statement | read ident | write expression | begin statement {";" statement } end ] ;

expression: [ "+" | "-" ] term { ( "+" | "-" ) term } ;

term: factor { ( "*" | "/" ) factor } ;

factor: ident | number | "(" expression ")" ;

call: "call" ident ;

if: "if" condition "then" statement [ "else" statement ] ;

while: "while" condition "do" statement ;

condition: "odd" expression | expression ( "=" | "#" | "<" | "<=" | ">" | ">=" ) expression ;

ident: letter { letter | digit } ;

number: digit { digit } ;

letter: "A" | "B" | ... | "Z" | "a" | "b" | ... | "z" ;

digit: "0" | "1" | ... | "9" ;

其中，program是语法分析的入口，通过递归调用其他规则来解析整个程序的语法结构。您可以根据这份伪代码画出PL/0语言语法分析程序的流程图。
