1判断语句
/ H" n& G! D* Z/ q8 j& \ if <condition> then* h& m& H4 ~7 s) W: z, A
<statement sequence1>;
* n) \1 k/ ~; |+ H5 [ I; _ elseif <condition> then
" s4 F9 B8 j# @+ V$ K <statement sequence2>;

<statement sequence3>;
1 Y# v% w S2 ?- Y w end;+ E5 n0 B/ Y# J& c: y5 m$ c
如果分支比较多，用：
( ~6 }5 P6 U. ~ inspect <expression>1 i2 p- l8 b8 P, u$ p; d
when <constant_list> then2 w3 X1 o+ s! Q. D
<statement sequence1>;# q6 d# t0 L5 \: y) k! \
when <constant_list> then, Y. I. c: T# C N& I
<statement sequence2>;8 @) N/ C0 B2 Y
...

以上为常用的函数！
