1判断语句
' K/ E! z" o% E; b if <condition> then, [ A* B3 | V4 M8 b6 b
<statement sequence1>;. K0 G% _, j& `2 ^% l* ]
elseif <condition> then
7 [. X5 k! I. b& U7 i/ e/ g! g <statement sequence2>;

end;1 c: U2 M u( v$ g; c& A
如果分支比较多，用：
: u1 _9 P1 `* ]4 F! D% G% w inspect <expression># S, a! S0 R. H0 c0 L3 [- \
when <constant_list> then
# a: a) M0 S5 A' x. S <statement sequence1>;9 H9 y3 p) l, V5 i$ P Y- Q8 N0 r
when <constant_list> then, y: L& ]0 i0 P% o3 c6 Z8 A

以上为常用的函数！6 E- ^6 D0 e( n6 {1 H
还有很多，如有需要我把资料发到你邮箱里
