[amibroker] Re: Are dynamic arrays possible in AB?

["trb0428" <tombrowne34@xxxxxxxxxxx>]

Hi Graham,

I am using the Osaka plugin to rank and sort a list of stocks.
>From this, I am trying to create an indicator which will display the 
rank of the stock for each bar. I have 200 symbols that I am sorting 
and rankng.

Below is the code I am using to read from the Osaka table into a 
single array ( only works for one ticker). I was hoping to be able to 
create (dynamically) the 200 arrays I need to hold the rank numbers 
for each day for the 200 tickers using something within the loop like:
       
myarray = "ID"+n;
myarray = ID;

but I know this doesn't work.

Can I accomplish this with VarSet/VarGet as you suggest?


for (n = 0; n<= tickers-1; n++) //n is the rows representing tickers
    {

     for( j = period-1; j <= BarCount-1; j++) // j*2+2 holds the rank
         {
             ID[j] = osTabGet( n, 2 * j + 2, mytable );

          }
       myarray = "ID"+n; // <-- this does not work
       myarray = ID; // <-- this does not work
    }

Thanks, 
Tom
