Buffer start at 0

Trying to get a buffer to start from 0, as opposed to the calculated amount.  Below is a simplistic example where the initial value (1000) will reflect the close of the current symbol.  I'm trying to get it to start from 0 and show the movement from that point on.  Any help would be appreciated.  Thanks

 

     int k=1000;

     while (k>=0)

     {

     ExtMapBuffer[k]=iClose(Symbol(),0,k);

     k--;

     }

To clarify a little. This essentially shows a 1 period moving average, back 1000 bars. Now the issue, on the start bar (1000) it's taking the calculation as the start for the value on the indicator. I'm trying to figure out how to have the initial bar have a value of 0, as opposed to the calculated value, then bars 999->0 be calculated value of iClose(Symbol(),0,pos).     Bar1000 = 0;    Bar999 = Bar1000+Calculated;    Bar998 = Bar 999+Calculated;     etc.
