請問寫法
請教個問題：如何將以下程式改寫為不用迴圈的寫法？
FO:=OPEN;
FH:=HIGH;
FL:=LOW;
FC:=CLOSE;
<%
vo=ffl.vardata("fo")
vh=ffl.vardata("fh")
vl=ffl.vardata("fl")
vc=ffl.vardata("fc")
last=ubound(vc)
vc(0)=(vh(0)+vl(0)+2*vc(0))/4
for i=1 to last
vo(i)=(vo(i-1)+vc(i-1))/2
if vo(i)>vh(i) then vh(i)=vo(i) else vh(i)=vh(i)
if vo(i)<vl(i) then vl(i)=vo(i) else vl(i)=vl(i)
vc(i)=(2*vc(i)+vh(i)+vl(i))/4
next
ffl.vardata("fo")=vo
ffl.vardata("fh")=vh
ffl.vardata("fl")=vl
ffl.vardata("fc")=vc

KK:=IF(FC>=FO AND (FC>=REF(FC,1) OR REF(FC,1)>=REF(FO,1)),1,IF(FC<FO AND (FC<REF(FO,1) OR REF(FC,1)<REF(FO,1)),-1,0));
今日折:=ROUND(IF(KK=1,MIN(FC,FO),IF(KK=-1,MAX(FC,FO),IF(REF(KK,1)=1,MIN(FC,FO),IF(REF(KK,1)=-1,MAX(FC,FO),(FC+FO)/2)))));

原碼:


fo:=o; fh:=h; fl:=l; fc:=c;

fc[1]:=(2*fc[1]+fh[1]+fl[1])/4;

for i=2 to datacount do begin

  fo[i]:=(fo[i-1]+fc[i-1])/2;

  if fo[i]>fh[i] then fh[i]:=fo[i];

  if fo[i]<fl[i] then fl[i]:=fo[i];

  fc[i]:=(2*fc[i]+fh[i]+fl[i])/4;

end;
