如果分支比较多，用：
: ~! x; n# _6 }! ` _+ v. T inspect <expression>- ?3 W* D0 Z$ x B
when <constant_list> then2 K5 Y9 r% P7 n$ Y
<statement sequence1>;
% v$ q) N0 X; M9 K when <constant_list> then
( P9 ]4 K) Z7 v6 [* b <statement sequence2>;
v% K3 f! C, v" @' ?% [ ...
7 Z1 Y7 i$ k' f% J' {8 A else
) O7 [9 B) r* s8 d) h, {$ R/ j <statement sequence3>;/ ^/ F/ }, j+ N
end;' q. u9 }1 {; H& ^/ ~7 ?- h) p

以上为常用的函数！
4 z' z& n- i1 f5 y3 [% X8 m还有很多，如有需要我把资料发到你邮箱里 ; C& N+ m+ S6 o" g5 x3 L/ x
