else
7 N. e4 n4 Y' w i( R <statement sequence3>;9 }8 ?* A& Q4 Q& J1 U6 n! y
end;
: y) L0 t8 U# m& S如果分支比较多，用：
4 ^7 {/ A5 V0 U4 w7 b, r7 q inspect <expression>) o3 ~( }& l. f6 z* K- @" ]
when <constant_list> then
# O6 d' r, ?: M% ?, O7 S3 G" z <statement sequence1>;4 a# W9 p w# v$ {! h

3中断语句

0 k9 b, a- L" F$ `( [/ P5 p Q/ j. ^1 H' q+ t0 e: Q- C
以上为常用的函数！
' m( C* g( q J9 F% z还有很多，如有需要我把资料发到你邮箱里
