1判断语句
. X! H0 W" v: o/ w/ R0 e, M if <condition> then: l4 E8 B- d5 ?
<statement sequence1>;
* l& k8 s% S3 t( C; _! j+ b elseif <condition> then
1 J. [8 l; ^" t! o5 Q3 W <statement sequence2>;

+ a; N, z4 W4 R1 r( e/ f o <statement sequence3>;
: S0 b$ T: u4 X: v# J end;! q# ?8 d$ V0 E# [+ X8 k2 E
如果分支比较多，用：
i# v* i* ?, V s2 Z5 z inspect <expression>
+ x- t9 u* K6 |$ y3 l7 o when <constant_list> then
- s+ d8 P& `$ l( b <statement sequence1>;

<statement sequence2>;/ F; k4 n0 V% F% T
...9 G5 o1 r3 U0 `
else. V: ?4 s; X- a
<statement sequence3>;1 t( ^7 z2 X4 u1 x$ `6 r- b
end;; v# B' a) y5 ]4 A) p2 U" n
; {# p* `! g& c: A; U8 l
2循环语句

还有很多，如有需要我把资料发到你邮箱里
