如果分支比较多，用：
4 y7 b% F, G2 b0 ~# E inspect <expression>
/ j% h, n& _2 a6 U# d when <constant_list> then
- G. Z7 ` [8 ^( N r) H# u7 p <statement sequence1>;$ p) s! J* a* K) Y' i: E+ w
when <constant_list> then
7 F* O. ~; J( B8 ` <statement sequence2>;

以上为常用的函数！
! z( y! t/ r5 k/ x, f5 L还有很多，如有需要我把资料发到你邮箱里 ; }) _8 v4 @" b# T5 m4 q
