1判断语句
3 d$ ]0 S { j, r: u if <condition> then
1 F8 v2 d+ Y w% C1 o7 ?5 z <statement sequence1>;4 Y. N% Z9 X/ e
elseif <condition> then3 n( ^, E7 ~! g' ]8 O

<statement sequence3>;( j. |( C' n% o8 s: t6 S
end;) V. ?4 |& K) r8 p
如果分支比较多，用：4 G% ^; F4 f; T5 n: a
inspect <expression>
# y' n: c5 B l1 w- i" E) | when <constant_list> then8 r0 N' B- D. u- J. Q9 G* m

when <constant_list> then0 n$ }4 t4 Y' m

...0 }8 c) i* v& W+ E, |' s( y
else* y. ], t/ e1 z% S% e# x

2循环语句

2 ?+ L( j, ^: A0 l: ~6 M, Y6 z, C- r9 e$ o+ R# ?
以上为常用的函数！
$ Z6 |4 w) C' o还有很多，如有需要我把资料发到你邮箱里
9 s. W+ d! g; i# o9 Z- ^( `3 e) ^' `0 J
$ h' |3 U0 ~" L$ [8 v b$ \) V8 K' @( U
