如果分支比较多，用：
9 L6 p1 b6 a- L4 c9 i2 J% w inspect <expression>
- V7 H( f1 U- B# {5 f' y when <constant_list> then
: L* ]9 ?9 q) P( o. ?/ X$ @$ ~ <statement sequence1>;

2循环语句

3中断语句# U; j* @) ^5 F3 ?) L
waituntil <condition> prio <integer expression>;
$ [) c1 R( R: r$ k$ N
: U' ]) N" Z9 e/ {- ~
) t; B+ S4 j+ I" S以上为常用的函数！
' q6 b+ t% p5 {* c还有很多，如有需要我把资料发到你邮箱里
