1判断语句
* B- a8 p A- {# \; p if <condition> then
5 i4 _+ B) ^* ?; e3 Q! w6 {. T <statement sequence1>;
% x- c& b' d6 Y$ k8 D, W elseif <condition> then

<statement sequence3>;* o6 B/ L9 t* \+ |4 y2 p5 O
end;7 T. D) s% S# D+ E! G$ \
如果分支比较多，用：
" r( M1 _4 e2 @, D. u5 [ inspect <expression>
* v2 _/ v2 Y# x" T2 u5 h" y" M1 m when <constant_list> then: N( b5 z, M! I' H; [
<statement sequence1>;7 X& Y' u) l N) ^
when <constant_list> then8 W6 J( ~' A" e$ Q2 ]
<statement sequence2>;; k# M) A& ^5 u- O3 H, U
...
" F' W0 {9 j& u# T# s! ^ y else
9 e8 x6 Y! U/ d3 P <statement sequence3>;! a$ K; S+ _ p2 N( i# z$ K/ l0 y

以上为常用的函数！
9 h* h# }6 g# y$ G6 Z还有很多，如有需要我把资料发到你邮箱里 & F1 l6 d; d: t
