1判断语句: O8 d* M' S1 J
if <condition> then
$ F9 A: j8 X2 K" T0 F, L" u/ Q8 @ <statement sequence1>;
! Q$ n: \% {2 I. z- {3 D8 e elseif <condition> then
% i7 i" r3 ]8 ]" z. L7 x) } <statement sequence2>;

end;" n" F1 V9 ]; ]" x; d
如果分支比较多，用：
. I. R4 o& h8 q# E5 W" v8 Z) w# b inspect <expression>0 X! r; t6 ~' F, n
when <constant_list> then
! a6 ^3 i$ l9 d <statement sequence1>;. z+ Y [+ j7 {$ w! z% o

以上为常用的函数！6 G+ K u6 }5 X9 g
还有很多，如有需要我把资料发到你邮箱里
