1判断语句
4 ? i' q* v0 @) l2 M, O7 ^ if <condition> then1 p1 j+ N* \9 x- l
<statement sequence1>;
" t2 e) o) Q7 b" o [ elseif <condition> then
" H% ]$ J& O# m( {) g <statement sequence2>;! P6 M8 O% w; X# r
else
# p- b7 b; B1 F1 @ <statement sequence3>;
- S# ^: R! v, f& s* I end;- M8 e4 k0 V0 c8 _; J3 f; ]0 A0 E
如果分支比较多，用：
0 Z- _9 }/ D& n inspect <expression> `. T+ f* r( _" ]* o
when <constant_list> then
& M3 I5 p$ h8 A6 `: G& S3 h <statement sequence1>;6 Y1 W( X, O8 M# Q+ R4 `' }7 G9 p
when <constant_list> then# O; o5 p, n* Q: z2 m2 ?% T& L
<statement sequence2>;
; t3 l8 F% ?# X4 I2 r { ... C+ r, [* ^% D( H) E' M- j6 a
else \, U. U( C! S+ ?( T
<statement sequence3>;" D) {9 _/ V7 F Z7 Y
end;( s, m6 C7 G/ |- l6 t
- k) X- @- C+ g' x# T
2循环语句

以上为常用的函数！( w* A, _9 j/ t2 W, o: x# }2 O
还有很多，如有需要我把资料发到你邮箱里
