1判断语句
- b7 I* b+ Q; j if <condition> then6 ?* k6 p% l. P8 ^5 w2 X( h
<statement sequence1>;' {* S& D1 {/ i8 F' g& o
elseif <condition> then& N6 i$ L0 c" Z6 i7 `7 A8 W

+ G1 F1 z9 e0 Y4 g" A <statement sequence3>;. s& o! s/ L4 `/ u$ ]
end;) m4 c4 n% p; `( O9 R7 P
如果分支比较多，用：
$ ^: {' ]* D& }5 D3 x1 }! S inspect <expression>! a+ ^7 V0 m& I, P
when <constant_list> then; c* i5 }7 P! J% i( D
<statement sequence1>;, ~7 Y/ s3 Z: |0 P+ E U
when <constant_list> then. l7 D" Z4 `4 q$ ^
<statement sequence2>;
8 f# x2 t3 F$ M+ F ...
7 \$ p7 }6 m* `5 k: r else
& R3 G+ r- S( K( G1 B <statement sequence3>;4 e# B% T! k6 \' v4 a
end;1 v8 _. r" B0 T9 ^ K

2循环语句

end;
- `9 N L+ f" a! g) I5 U (2) while <condition> loop

3中断语句

以上为常用的函数！9 V- I1 R2 K0 n% m7 b% k1 S$ X
还有很多，如有需要我把资料发到你邮箱里
