1判断语句
5 [' ^- p, ` `7 D8 |) x [ if <condition> then9 y a' n" o5 L1 @9 B
<statement sequence1>;
2 s! @ R* N4 _. e elseif <condition> then7 P' C0 W3 t K W( k7 Y3 D9 X! ^
<statement sequence2>;
3 a) X) u6 ~* l' K" ?% X# a else
1 z6 E% }! }1 Y, I- i/ y* X9 O7 O <statement sequence3>;, v6 U+ i" _, I
end;/ ?! C3 q1 y$ G
如果分支比较多，用：
% ]# _ x3 _$ o1 _' {0 U' Q inspect <expression>
6 y! A+ j& C: j! f5 P7 d* M3 F when <constant_list> then
, @3 |' ^/ I+ q7 s3 ]5 u <statement sequence1>;( _; S: ^# {, n, ^' L$ {8 F
when <constant_list> then
; J$ I0 i8 h" H <statement sequence2>;

else, z* m! g$ `& R m7 n& O
<statement sequence3>;- h9 \, v4 ?7 }9 y7 B! G
end;: I. I" T0 w9 Q" f% m

以上为常用的函数！( d( G* F1 |& Q
还有很多，如有需要我把资料发到你邮箱里
