1判断语句
! A' T. V. W3 K7 s) t if <condition> then/ x- O- J$ E# l6 g+ E
<statement sequence1>;
" Y' V# n& R! c; i elseif <condition> then# T$ S& B+ y" r- U3 f5 s

else + L" W6 Z. b5 J9 L4 T
<statement sequence3>;
" f- \' K- b. ]' s$ u3 k end;. S' E6 W K- z' u
如果分支比较多，用：
! z% r* h; Y3 U inspect <expression>- M5 ]4 ?# z3 t3 A5 `, c, l
when <constant_list> then/ r7 X1 h6 c+ _2 z8 |2 ~
<statement sequence1>;$ ?/ E" B/ | [4 h, r: j
when <constant_list> then- }8 m* ?" ^5 a
<statement sequence2>;6 l# E& d7 K5 n
...2 \3 f. g' o: v
else
. i; o) j. t1 H <statement sequence3>;
2 F9 Q W" t+ p+ f+ S! F1 zend;

2循环语句

end;" v: ?: F9 d0 d1 Y
(2) while <condition> loop

3中断语句

以上为常用的函数！
* m. Y; _, [8 g A( z/ j还有很多，如有需要我把资料发到你邮箱里
$ \: w. P( r4 u: q' |& t7 o3 M
