1判断语句
3 i9 o4 W' b F3 |+ Q- | if <condition> then
. p% M4 D7 }* M+ ^: E <statement sequence1>;
3 j& N. f2 E% N elseif <condition> then# d+ b" [1 }" e# f# }
<statement sequence2>;
3 @3 w$ G0 k6 _- W" e1 W. j else # ]4 F7 Q; O5 m- A- Y+ i
<statement sequence3>;
9 f5 h$ Q/ F% X S end;( t' Q9 ~: S: W/ I4 M
如果分支比较多，用：
, d0 M, O( A7 {+ p) V inspect <expression>
2 ~1 y" \. S) p( F5 { when <constant_list> then
5 g D: r/ Z$ B ~3 N <statement sequence1>;' W7 w/ z, T" H/ S6 n. g. M" p) R
when <constant_list> then
& K" h2 ] j8 H( ] y* s% G1 m% ] <statement sequence2>;
: n7 f4 [0 b' k- d ...# O2 z$ s2 ^3 U0 |9 b

7 {& t4 Y6 r+ }0 L' }+ e S/ J7 o! v7 k W8 I. t( W4 m
2循环语句

until <condition> loop
8 p8 i W% k4 U- f5 `, u <statement sequence2>;4 X( s, O. r' M
end;
3 P: |% p1 J7 x* s0 L+ a: F+ v- |; L/ } (2) while <condition> loop
; v" c3 G( B+ R* V- Y0 \# @ <statement sequence1>;/ \9 o* |) w. v+ R
end;
7 Z" L, e4 a. h2 Q (3) repeat

1 o0 S/ P2 i" m, t( j( X9 x until <condition>;* [; z8 D5 A7 I! d- m7 s

3中断语句7 }7 h; v. i% r- ]$ D
waituntil <condition> prio <integer expression>;
' b& S/ B5 J5 I0 e* X3 _* f, ~ N
2 \, z, @ p4 ]& p# ~1 l z2 c2 g( G7 b
以上为常用的函数！
' C8 z3 W4 v+ A+ M还有很多，如有需要我把资料发到你邮箱里 9 G( N! D8 a. x) A6 m
) y8 G" O# U8 `1 t. D, |+ T
