[amibroker] need help am relative new here

["rijnaars" <rijnaa@xxxxxxx>]

I have a nice formula which plots de relative performance of a symbol 
against the dowjones.
i like to be able to shift the results to a list in order to do an 
exploration. i believe i have to use columns in the formula but do 
not know how to write the correct way. Can anybody help me
this is the formula i use

_SECTION_BEGIN("Relative Performance");
_N( TickerList = ParamStr("Tickers", "^DJI,$INDU,") );
NumBars = 20;
fvb = Status("firstvisiblebar");
Plot( 100 * ( C - C[ fvb ] ) / C[ fvb ], Name(), colorBlue );
for( i = 0; ( symbol = StrExtract( TickerList, i ) ) != ""; i++ )
{
 fc = Foreign( symbol, "C" );

 if( ! IsNull( fc[ 0 ] ) )
 {
   Plot( 100 * ( fc - fc[ fvb ] )/ fc[ fvb ], symbol, 
colorLightOrange + ( (2*i) % 15 ), styleLine );
 }
}
PlotGrid( 0, colorYellow );
_N( Title = "{{NAME}} - Relative Performance [%]: {{VALUES}}" );



_SECTION_END();
