end;& U" K8 G" |( Q# p# `# ?( d
如果分支比较多，用：
; w- c! T8 r9 z( p inspect <expression>" ^7 S4 l2 j0 H3 q5 D
when <constant_list> then0 l# H4 e. f9 a6 t; N% L$ [
<statement sequence1>;4 `( L& w; i, U0 I4 A

...8 @ F: q' H# F, W& b

以上为常用的函数！
* ?& @% ]% ~# B% X( p% k! `还有很多，如有需要我把资料发到你邮箱里 $ V/ a+ b8 V8 @( C
