在使用Order List时，当一个order list满足不了order的数量，要用第二个甚至第三个order list，有一段程序，请大虾解释一下，多谢！程序如下：8 ]7 M7 F/ W* k N8 ]( E# ~
begin P_Order arriving procedure 0 D" |9 C+ ^6 e0 } set V_NumWanted to 10; k6 B5 k7 b3 v: `1 U! Y
set V_NumOnList to OL_List1 current value 9 r9 e* f5 G4 V3 R5 m order V_NumWanted loads from OL_List1 to P_NextProc 2 G4 y9 A. U; a% Z in case order not filled + k/ `8 ^6 p! C/ X9 d begin 7 q7 K7 J" } Z wait for .01 sec% n. k7 s, s: m- l. Z
decrement V_NumWanted by V_NumOnList - OL_List1 current value" i" s0 `) P! a" x" ~4 x7 H
set V_NumOnList to OL_List2 current value9 \( ^) m) p1 `1 t4 x
order V_NumWanted loads from OL_List2 to P_NextProc. ?9 S$ U6 D" z M: |
in case case order not filled9 m" ~; e. q! G% I
.................................................................# A A$ T* d9 E& u0 [4 d
/ T) M+ ^) M2 @! _0 C
- x/ l0 O2 v [0 e1 |6 p5 D" h' | t
我就是不明白上面用红绿色作标记的那句，为什么后面要加-OL_List1 current value.用前面绿色部分，即把不够的load算出来就不行了吗？
