/ l+ f J+ ~( i3 l; X1 G) w if <condition> then
( i0 T6 P% e% T1 K( g6 ^2 J: N <statement sequence1>;4 {) Z8 v0 q0 B+ D! d

<statement sequence3>;
- c9 G& R$ D- a7 g end;5 g: M! S; Q" M. b# w: Q( f
如果分支比较多，用：
8 @+ S" G9 Y7 y- U$ i% J# I/ L p inspect <expression>) r" M: ?1 i4 f k& \7 }: m/ k
when <constant_list> then
; Y# k' q0 b J7 j* A2 s+ A" | <statement sequence1>;
m$ C( g- M; @: Q) Z$ Q when <constant_list> then
9 y9 W7 _7 L8 B2 i <statement sequence2>;& i; E' ?* s9 g5 p% @% B
.... w0 f/ G+ w( C# `/ V6 e
else
' O4 h. r. V C! W' w <statement sequence3>;8 B' @: Y, y& n) i0 x' g& Y
end;

以上为常用的函数！
+ c: i4 i5 i- Y- ~2 t/ p还有很多，如有需要我把资料发到你邮箱里 7 \+ G' ^" W) u j! b+ ~( u
