[amibroker] Re: Arrays handling

I am trying to fill in an array (j) with 0 to 50
so that the last bar is 50. Tried this code below but
doesn't work. Please help

prd=50;
Lb=LastValue(Cum(1));
fb=Lb-prd; //fb is the bar to start, so fb should show 0

j[0]=-1e10; //empty array
k=0;
for(i=fb; i<Lv; i++)
{
j[i]=k;
k=k+1; //increase counter

}
Plot(j,"",1,1);
