1判断语句
5 c& M- L; _3 @ if <condition> then
: k* }8 T2 I& M" E6 k <statement sequence1>;, `+ [: Y1 }! u4 }$ h! y
elseif <condition> then
9 _; a* y! Q+ t. w9 a <statement sequence2>;! _& `- a( _& U9 \; }
else ; M* e7 }0 S/ L+ S9 B8 d/ |
<statement sequence3>;! c; h, b4 u4 I j. Q+ t" c
end;
! a d, P t4 d& w, W如果分支比较多，用：7 K8 I# A z; `1 `
inspect <expression># x9 J+ n) z# n/ W ?9 T
when <constant_list> then5 Q+ Z6 F& ~. q R' i
<statement sequence1>;

2循环语句

3中断语句* T! R# l. }: J; M* k. b

以上为常用的函数！
. }: [9 ~8 ?3 s! R. I还有很多，如有需要我把资料发到你邮箱里
