1判断语句$ g, M& k3 ?' g. B* Z7 P: {3 V
if <condition> then
0 J- C3 J- g, t2 Y; U <statement sequence1>;

5 A+ A$ @' a0 m: W, w <statement sequence3>;
% ~% `- M- ~! M- o, y end;; T1 h: ^, t5 {7 z1 x) t! \( _
如果分支比较多，用：
. [( o: G+ U7 B) t8 { inspect <expression># h7 N8 Y$ S0 A# {6 V* Q
when <constant_list> then! }' |/ @9 x( p
<statement sequence1>;
`8 T' n3 S/ c when <constant_list> then
