1判断语句3 z4 i- d4 ^$ n G' l" E; J
if <condition> then% l S& S7 c. ?( u( i: v

end;' n) }# }0 M, a, I" T& @) y
如果分支比较多，用：
( a5 a$ b* F0 b( t' q) { inspect <expression>- p7 [; l" H/ M3 C/ w9 u
when <constant_list> then
2 k H/ j/ V Y& e9 u' y <statement sequence1>;6 B; M: E- \+ h' O6 Z

...

以上为常用的函数！" C) n: O- s! L& S& Z
