1判断语句
6 b2 B( `+ }0 i( h% ?! S if <condition> then
5 m0 H& l1 S% r& w <statement sequence1>;- R2 |! y2 [6 ~ T3 R% G
elseif <condition> then
' I9 M m& B3 K4 e2 N <statement sequence2>; K5 ^5 Q5 @" ^; S
else ! B3 b3 S$ r: B! T. @
<statement sequence3>;
& A D$ K. P9 O3 r1 _ end;; L# \5 m( I9 B, U
如果分支比较多，用：
6 [+ f$ ]9 h8 l _: a( H( [2 a# L inspect <expression>
" ?2 [0 b" ^' P" ~6 Q2 V; F5 x when <constant_list> then
5 i, T `' V% ]6 b* L# Z7 C, i" c <statement sequence1>;5 o5 b& k1 i1 A; }' _/ \
when <constant_list> then

M. E* D, h5 _ ..." Q% M# A# N( ^7 U5 B7 [. R, \8 g
else

以上为常用的函数！
& ]3 A! v( W, j6 Z, i, P还有很多，如有需要我把资料发到你邮箱里
