Thanks Herman.
For those who wanted to know the difference between a
function and a procedure, Herman's function below can
be run as a procedure since it doesn't return
anything.
procedure PlotNormalizedTicker( Ticker)
{
array2=Foreign(ticker,"C");
scaledArray2=100*(array2/ValueWhen(firstBarVisible,array2)-1);
Plot(scaledArray2,"\n"+Ticker,ChartColor++,4);
}
