1判断语句

end;- L, c: _! |! O2 E3 E: e
如果分支比较多，用：
$ O* C3 ~: r- o9 A9 H) I# q inspect <expression>
3 C2 }- p* F2 L2 y; U when <constant_list> then' f- I: h2 J, w& ^
<statement sequence1>;2 z* q) s8 c, \ p6 h+ B
when <constant_list> then
5 A5 s; z) l4 D0 y) C# E <statement sequence2>;" M9 Z1 ` j5 p G/ G
...
% B+ ]+ U; u& r1 t( m else% {; u; J/ v/ p; ?* p6 Q" q
<statement sequence3>;
# p" f( i+ y# D' G5 Q' a4 Mend;/ H! D# B7 X' x0 K- m+ }. t4 ~

2循环语句

until <condition> loop

$ @9 [" R9 o h5 J" K' ~
$ U0 K% V; \6 k( c7 Y, x( C: l5 y, T2 q5 A
以上为常用的函数！
! X) x$ Y1 _6 j+ J- _还有很多，如有需要我把资料发到你邮箱里 # {* w0 I/ U( ]. w/ {
1 ^# `! T* w' W1 C' c2 [4 a- v
m4 ?5 m) s7 K7 U+ F' U0 f6 z0 I: a3 C
