1判断语句
8 J# ~. B% P2 z$ y5 o if <condition> then J, [8 ]5 p1 Z, _( q& U

3 l6 }; e# n6 [4 K8 ^* W <statement sequence3>;; ?, y1 h1 K5 R4 f
end;7 Y' B1 {, j# `; b/ @6 ^
如果分支比较多，用：
7 @, y: Z9 R; H6 K0 J inspect <expression> r5 H3 D+ c% `: u3 x
when <constant_list> then B* |: X% A1 w5 ~0 L
<statement sequence1>;1 [+ C7 \% q# a1 m% E
