1判断语句
z& T s/ r/ C if <condition> then
u3 G$ z& R! p# V" l <statement sequence1>;$ I }2 p4 o L* \1 _2 @
elseif <condition> then
6 m4 }8 C# y9 X; r$ q4 ` <statement sequence2>;
. z! [8 ^, y: X8 F q else
m0 W* a, m, d3 t <statement sequence3>;
+ d- m$ T% x5 b/ N: P( F end;- |3 i! F/ o7 b: O o( f3 D5 ]# v
如果分支比较多，用：
" p; u3 F/ r+ O6 T' I inspect <expression>' P3 J2 g) [0 f( H
when <constant_list> then
: U5 t. o, n' m6 U/ H4 A0 t2 [ <statement sequence1>;% A! Z/ u H$ B/ M
when <constant_list> then
6 U/ u7 R: a5 A! s: C% p5 n7 K3 E <statement sequence2>;$ e" L: G0 h# ?) c" O1 B0 w
...

以上为常用的函数！
v A' D. E/ D' l |5 W; N还有很多，如有需要我把资料发到你邮箱里
