1判断语句
4 t, a3 S& s- o if <condition> then% ]1 a6 C% [% d0 O! s$ ?

elseif <condition> then
3 g9 d( n- u# e9 A p <statement sequence2>;( ^, {: ~$ p$ p0 A+ k5 c
else
/ P; Z+ N1 P9 C, d3 j <statement sequence3>;
4 L* x2 x& x; J6 c2 v% ~% I end;9 S! O* P( z! E. w' M
如果分支比较多，用：, u% J i+ y9 B8 K9 ?
inspect <expression>
2 F- K& K0 X0 B9 r! X. ` when <constant_list> then

3中断语句

以上为常用的函数！4 o' O& N" b' s1 X. Q& [
还有很多，如有需要我把资料发到你邮箱里
