1判断语句
% K: i6 G* z E if <condition> then: Z: i5 |: Y* i
<statement sequence1>;
+ G; S$ W" T3 Y% E7 S7 }' |) @ elseif <condition> then1 a) m' E2 e( a: j9 ~

如果分支比较多，用：
/ s) H. P4 m' g! m* d inspect <expression>
3 ?5 b* Q5 d4 R. ^" w) m when <constant_list> then4 m* S {$ `9 e
<statement sequence1>;
( y2 {6 ~' D$ y* b; U when <constant_list> then

+ d/ e# S. L. Y: _. A; v, i还有很多，如有需要我把资料发到你邮箱里 $ X( y% V+ }! Y H* x5 K6 @
