XX1:=WEEKDAY=5 AND REF(TIME,1)<160000 AND TIME>160000;

XX2:=(WEEKDAY<REF(WEEKDAY,1) OR (DAY-REF(DAY,1)>7)) AND (REF(TIME,1)<160000 AND REF(TIME,1)>090000);

XX:=XX1 OR XX2;

N:=BARSLAST(XX)+1,LINETHICK0;

XQ:=WEEKDAY,LINETHICK0;

JK:=VALUEWHEN(N=1,O);

ZZG:VALUEWHEN(N=1,H);

ZZD:VALUEWHEN(N=1,L);

 

 

既然是周首k，那么xx1是干什么的？
