1判断语句5 `/ [! k! l0 `9 l( j
if <condition> then! l! I8 a: ~! @/ r4 W+ a, l. L

end;% L2 d2 V6 s% z2 M6 U! ~! P6 K7 h
如果分支比较多，用：
6 L/ Y; e, B7 Z inspect <expression>
4 Y/ l( }: I& w when <constant_list> then
8 ^$ i4 a* g, a4 R, N- E# y: t6 b K4 A <statement sequence1>;/ U% S* T* p8 D* y1 a! S

2循环语句

3中断语句

5 e9 z* `+ X2 A6 f
/ I- l8 W* B& g. u, U以上为常用的函数！
+ [# o6 T! n, H8 H0 |' Q还有很多，如有需要我把资料发到你邮箱里
