赋值语句自上而下翻译系统的设计与实现.
设有如下文法：
S → A
A → V:=E
E → E + T | T
T → T * F | F
F → (E) | digit
V → i
采用递归下降分析法，并生成四元式-Design and Implementation of an assignment statement is a top-down translation system. Has the following grammar: S → AA → V: = EE → E+ T | TT → T* F | FF → (E) | the digit V → i recursive descent analysis, and generate quaternion type
