1判断语句
Y9 t& T7 h2 y! ~ if <condition> then
/ ?: ^3 j; C( o9 d" l <statement sequence1>;( N0 D, H- ~! m5 U/ ?: P
elseif <condition> then
# j- q- n H/ i2 W2 O <statement sequence2>;
; Z2 H+ M& c4 b% C1 } else
1 I5 V6 u- [6 D5 s1 _, U7 c <statement sequence3>;& Q. M9 `% O/ S3 N7 T4 D
end;7 b! }; z7 \. x4 b6 S7 f
如果分支比较多，用：
f3 u3 w m3 d! A2 G, f1 ?1 ` inspect <expression>; h% l, t' |7 ~" ` y' Z. ^
when <constant_list> then' c+ I- X4 n/ z7 Z0 u; z4 M
<statement sequence1>;
& X* e( k% S+ i# F when <constant_list> then* Y, p1 w3 i* C0 \" c
<statement sequence2>;% E# L9 G- S8 s& {
...
1 I( o! d9 G9 I9 F else
& M8 z3 p u$ }3 M3 k) o <statement sequence3>;$ |* M1 h6 t- X6 S
end;3 [8 k3 h8 U( M+ ~" \" B8 k
0 W* N9 g4 D9 u
2循环语句

# @3 _+ h2 M3 j until <condition>;
