$ v2 C F8 G- m if <condition> then0 [( H7 H( {: F4 M" m; f: ~: D

end;
7 p5 l( l ]. f+ m8 j2 l7 F如果分支比较多，用：9 q# D, Z! u% q: h% _
inspect <expression>
8 p' i( v! _3 ]+ x# }3 ^ when <constant_list> then

3 }; e0 L' b- H2 H' [ ...5 v y, p& P, a) u. u
else
2 s6 s- e, w. J: Z, D* A <statement sequence3>;7 I3 _, } f' Y' q3 P. J0 P

2循环语句0 w* y/ V2 C# E* g& y
(1) from <statement sequence1>

3中断语句4 e, I& C) U! j8 Z% Q @2 h: J+ r

. M) R" X8 e1 j; f8 I
以上为常用的函数！
$ s) x8 t3 h/ s! j6 D还有很多，如有需要我把资料发到你邮箱里
