1判断语句
( Q! W" I. r: C7 K5 C7 F if <condition> then
% u! e# Y8 L- R- i7 z- B4 t <statement sequence1>;
* r4 G/ V5 D# P elseif <condition> then: K* @5 W, f) \ {+ H, ~8 ^* K2 G
<statement sequence2>;& n% h% q2 [2 H1 I# D
else
- a* D! B) _3 I. c- u <statement sequence3>;, k$ E0 h6 e1 Z8 k1 Q" v. M- m
end;. w, }* ]+ V9 p3 ?3 V: Z1 M% Z
如果分支比较多，用：
- T( q7 s) [6 C inspect <expression>
3 g( z |( D: y! d: e: i! ? when <constant_list> then8 L. D3 U7 d' D2 I; ~; }4 j6 z( K
<statement sequence1>;
' f5 v- L3 |6 b$ k; d) g& U when <constant_list> then! T- [% h# w: r0 U. O
<statement sequence2>;
5 x" q# Y7 j6 c( I$ i ...8 l6 y k1 }* _9 }) k" R6 V! F6 s
else5 L% q- f4 O! y: L" e' B
<statement sequence3>;, U8 u; _! t g, K# P0 Y( B2 N
end;6 m( a; Y! z% `2 u0 c1 `

2循环语句

3中断语句$ `7 y5 u- A( E1 @ B; c! G

( H5 C' B; u4 x/ J* g+ ]5 F% h p+ {8 c, f6 t1 U- b. V
以上为常用的函数！. u' v1 H; L+ x
还有很多，如有需要我把资料发到你邮箱里
' N* E( B; O' ]7 M+ s8 h: j, E
