1判断语句- P; e3 g; z! z% ]
if <condition> then
, G/ |' p7 s4 Y& p% k! ? b# [8 X <statement sequence1>;& a# P% E- L5 d0 V& w

6 O$ ^9 @ Q) _3 P8 K1 u) E2 V <statement sequence3>;
2 g; S: p$ q2 M. d end;1 F7 R' e9 z! b9 F; U
如果分支比较多，用：

when <constant_list> then$ T6 m5 C% G9 t) D) S/ S- m3 ?

...

以上为常用的函数！
( S+ q5 w* k- K% x* |还有很多，如有需要我把资料发到你邮箱里
