1判断语句
+ ?1 j+ G& {2 i5 l if <condition> then
* L) p, E$ [) Z h4 S7 H6 B <statement sequence1>;

$ x, j; n3 p) B <statement sequence2>;1 u- K ]4 X0 `* u, a0 m8 [+ {! b
else 8 z3 B& P+ d# K$ j, A0 w
<statement sequence3>;
9 {% m' c; g9 g, H \4 f. F5 x end;- u: [2 V( Z5 s
如果分支比较多，用：
. [' r7 A* T7 l# d' ~) d* | Q inspect <expression>
, o) z! E' |0 N- N$ R when <constant_list> then, r4 O6 e# w; E- K" x
<statement sequence1>;
