1判断语句
% T- r& S) s: J0 E- _# K0 F8 r if <condition> then
- [9 w7 p$ N- a7 E/ ^4 ^ <statement sequence1>;4 a4 i: x/ J; ]$ S2 P4 G5 x" u
elseif <condition> then
& O! i1 Y3 e8 D' o <statement sequence2>;! V8 s% t- ]- F( A: i- |

<statement sequence3>;
# t4 H! M$ |* s/ |- p end;$ V9 g% G L# Q$ s, ^8 g* s: w; N0 V2 K
如果分支比较多，用：
: Y/ J$ L3 `% X5 {( {7 T; V9 q inspect <expression>- d3 m; z" `; |6 ]2 w& e& d, J
when <constant_list> then
8 ?8 [8 Q" R1 H. r: @ <statement sequence1>;. a+ A! K. V1 t8 Q( i8 f( M
when <constant_list> then
% m7 V# f, p% T <statement sequence2>;
) U5 {9 q" l/ O# T$ T* C ...
2 L8 r- I) D: T$ Y) I, F else
) B0 P2 H. y2 X1 j1 O) z D <statement sequence3>;( ?7 |( ]$ t0 d3 } B# f
end;
$ n( T7 y: F1 H: ?4 D0 c# ~2 I6 c% {% B) e+ i5 X; _* Y

3中断语句, s8 W. t$ G: Y/ G3 N

: o; `' B {1 J5 l1 w0 l% M, r2 E

以上为常用的函数！
# C0 T, o% h" V% T& q还有很多，如有需要我把资料发到你邮箱里
