1判断语句
* q G) g/ J' W, q0 [7 Q& _6 l if <condition> then
. F" u$ O: h: Z7 o% O1 ~/ f* B5 U <statement sequence1>;* ^- D3 z5 M9 x. Q1 {" B
elseif <condition> then

<statement sequence3>;" c& V v& V2 n% Z' ^
end;$ w; s7 r" \$ Y) ~6 f
如果分支比较多，用：
. K0 Z% y& a( F0 ]9 s inspect <expression>
" N) A; B+ T# {. E# t0 P when <constant_list> then
! p5 v9 n+ P! Z2 Q9 W5 z <statement sequence1>;" c" U! |; @! n! M% y
when <constant_list> then
* p0 R( U. ^) C8 v0 K4 ?" D: h <statement sequence2>;
4 E; s1 | x) B! { ...+ s* r/ l' t3 {- e1 _$ {4 |
else* s+ F3 g7 K) r0 A" @
<statement sequence3>;
# e" w9 n# }$ |end;; T9 A0 E' k# L7 h7 o

2循环语句3 s; h' v: a" A$ L

以上为常用的函数！
$ D8 r1 o. y2 ^4 K还有很多，如有需要我把资料发到你邮箱里
. m/ y9 o2 {% I* t# Y7 j; [4 L1 ?: {; _# Y
5 s, R3 U1 X* ?: z; Y
