1判断语句
. `. F: m% T$ H8 Q! M4 J9 C if <condition> then
6 e- V- J* I' N' K5 v' i <statement sequence1>;
! s! m$ {; ]/ D6 g0 N+ ~$ B elseif <condition> then
4 N3 h( [9 P% k# Y2 e <statement sequence2>;+ o; q. B9 ?) }7 V, T1 g E
else & f5 t; e3 c( M) `: @' ^% l- z
<statement sequence3>;, C: @& Z4 \2 c$ E
end;9 T$ |3 S; r$ R% E p" f
如果分支比较多，用：
( W4 M& q7 g6 I7 T2 J& R* b inspect <expression>
* p, E: k& P9 X8 W when <constant_list> then
* W+ K1 l2 D; D- | Q! a <statement sequence1>;
3 s% A0 Q5 @! s- s% y: g when <constant_list> then
, ^% H& b! }" {2 ]1 e2 B, Z: n <statement sequence2>;* [ n# Y/ } m* G% `
...0 D. F: A5 e! F) w6 ?) L
else
- h S% J& D5 B+ ], N0 ~ <statement sequence3>;" |1 a9 R R8 N' H' o
end;
3 x, ~, K+ t, _/ ^4 {5 S3 |. d' I) W6 |
2循环语句

3中断语句

以上为常用的函数！. o* p: J$ E6 x" o6 x2 @) g1 w
还有很多，如有需要我把资料发到你邮箱里
