1判断语句: Z& T, K- U- B" |
if <condition> then
- ^$ c; s4 w* D# b" P( { <statement sequence1>;! B8 W: i0 I2 Q. o

如果分支比较多，用：7 L/ Z0 | j# O8 n# G! C
inspect <expression>
% u( @4 f/ v$ ]& P* \" I) E$ O when <constant_list> then
6 t) h- J9 C/ d1 ~. T8 n; [ <statement sequence1>;" Y \! f4 F: ?; B! m
when <constant_list> then

以上为常用的函数！
- D! n8 O% c" v" \0 K( K& h4 `2 i还有很多，如有需要我把资料发到你邮箱里 % i7 z: H8 G K
