1判断语句' z9 f% j7 k5 t
if <condition> then
' N# w. V0 E) p& }0 f0 {5 H <statement sequence1>;
' U: S6 C1 W6 l+ p" \ elseif <condition> then

<statement sequence3>;
9 T' O) G8 h, e0 H0 _, a end;7 ?' m9 g9 s. Q7 q' \+ V/ o
如果分支比较多，用：

when <constant_list> then H( P8 v- D* T
<statement sequence1>;3 u# H2 v; _" B8 E
