1判断语句

" c) s! r5 |! k+ b3 a- `- G9 X <statement sequence1>;
& I# T# U9 _ h9 p# N% c* A elseif <condition> then

else
J# I: P- ~2 O S w* f <statement sequence3>;
1 o( x! w0 N8 k4 n- L6 Q end;$ P9 Y' U7 y* r7 A! g% s
如果分支比较多，用：
b( W4 o {7 E( Y1 l' v9 U. T1 R inspect <expression>2 S5 ]2 t7 Z! m* G
when <constant_list> then
$ S# |; Y! l9 K) h, w: z% c <statement sequence1>;' y! H" ?1 n+ R& R
when <constant_list> then. o! u/ o) H7 J9 m5 A# P
