1判断语句
: e4 A6 Q3 B% f; S+ X- i if <condition> then+ d; w5 `- w# L/ @1 Y- ?
<statement sequence1>;/ e D, o& d0 t' R( m
elseif <condition> then
6 J. x6 P3 x8 s* s2 W& o7 D. \+ s <statement sequence2>;7 }. K! b& b7 u9 g. M
else
E1 r, Y0 V6 q: d$ p: ] <statement sequence3>;
- p- w3 D; M v5 } end;% D( ]% h6 V2 n7 t% }6 J6 C2 t
如果分支比较多，用：0 o9 Y* [8 x- _4 A5 C* C' K
inspect <expression>$ M( ?1 _3 \3 U' E
when <constant_list> then! X" Y0 b; y; O# S9 A2 o
<statement sequence1>;
( w9 `) R9 c% T# M2 ]& U3 r when <constant_list> then
5 y; [3 o3 C4 X& h7 R, S <statement sequence2>;
! b4 x3 N' k" A; S) b ...
, }7 L+ n& f( c& B' i- g, O8 b else

以上为常用的函数！
+ z% b. J/ E( E( k6 T/ p还有很多，如有需要我把资料发到你邮箱里
