1判断语句
: H8 `2 _+ O3 P9 @% m if <condition> then
0 U- }- C7 p L6 ]" F( P5 T <statement sequence1>;
" {4 m/ w3 R$ m8 s elseif <condition> then
* [' f8 N4 G3 Z7 N/ { <statement sequence2>;

~7 L8 W8 {5 B. S$ E+ ] <statement sequence3>;
( h( y/ r) s: W) \; x end;# ^2 ~8 l0 G c- r# p, J+ [% Y/ k
如果分支比较多，用：
. B& Z3 \0 u$ E8 ? inspect <expression>, W- B5 u' `- L2 b! m
when <constant_list> then
, a" H" k' c8 p. H( e) A" ^- s <statement sequence1>;
. w3 @( E$ r) B when <constant_list> then ?4 N& J# [0 ^+ ]' W& P: Z
<statement sequence2>;
' @" `9 r% m4 V ...
" l8 R+ E$ ^; L6 ]; x/ M else: L2 |- p i2 c5 `2 V4 t! b
