如果分支比较多，用：
5 i4 g/ g7 x9 Y; x inspect <expression>/ g! O" k2 m, F8 Z1 U
when <constant_list> then
0 D: v$ Y0 w& x+ h <statement sequence1>;
; K3 Z$ a4 i7 D9 t% y. b when <constant_list> then
, `) u" z$ g" G J <statement sequence2>;
( U: o" R! a, B/ H) ~ ...
t, Z4 H3 ^- d7 s- S else
+ h, `# A9 j- A' P <statement sequence3>;

以上为常用的函数！
$ D+ I& Y: {% g" B3 D2 m& P还有很多，如有需要我把资料发到你邮箱里 $ H, ~4 a# ?! H0 {* Y7 T
