1判断语句
( m# k) z; U- {3 E9 C \8 M X1 J if <condition> then

else
$ [: ^ Q( b# f& w <statement sequence3>;; s( l' `3 m* R U) J

如果分支比较多，用：) T: e# A# F2 i3 J# P
inspect <expression>, e/ u u F7 R! @$ b! ?# k( y% E; t, j
when <constant_list> then
5 H/ J; [( H# P$ \& {' _ <statement sequence1>;

以上为常用的函数！
: P+ q' l# j V/ Q还有很多，如有需要我把资料发到你邮箱里 4 h, G+ r; F. d$ j
