1判断语句
7 ]% g/ E4 s+ M* ? if <condition> then
1 a6 ] n/ T/ l( z/ H; F! p <statement sequence1>;" n8 I8 q4 n; a& ?

1 j" V( h! M% S p else # v0 E0 Q6 J$ v2 j- D

end;, r, A8 p$ ~8 I8 d8 P
如果分支比较多，用：
! X4 M+ a1 j) Q, r inspect <expression>
- C# R$ g+ ]. H* M0 x3 n e when <constant_list> then
% V2 t7 D6 Q4 E2 d <statement sequence1>;" W7 z& [" K4 _
when <constant_list> then
; v* X: c6 g n: m <statement sequence2>;
5 s) L5 X5 u m+ f ...0 ^, U6 ] g6 _% ?! I( B
else

以上为常用的函数！
5 ~9 j% ?/ }. Q* z, a还有很多，如有需要我把资料发到你邮箱里
# |0 z8 {, i0 ]' Y" @2 u/ D1 n9 ^7 P: O
