Tomasz,
Once again, I have run into the limits of my knowledge.
The following code is what precipitate my original question. The
addcolumn example you gave below works just fine. However, If I try
to do the variable PerChange, I run into an error message that I
don't know how to fix. BTW, it works ok if I use
the "NumColumns/ColumnX=" approach.
So my first thought was that it was the array/scalar difference that
was causing the problem. But apparently not.
Can you help me with the difference as to why addcolumn isn't working
here. Its something I haven't yet figured out.
Thanks
Bill

Filter = 1;
DateSpan = EndValue(BarIndex()) - BeginValue(BarIndex());
Range = DateSpan ;
PerChange = WriteVal(100*(EndValue(Close)-BeginValue
(Close))/BeginValue(Close));
SD = (StDev(Close,Range));
SDPerCent = (StDev(((Close/Ref(Close,-1))-1)*100,Range)*((Range)/
(Range-1))^.5);
Title ="Percentage change of close is "
+ PerChange + "%, \nStandard Deviation of actual price change over
the period is " + WriteVal(EndValue(SD)) + "\nDaily Std Dev of %
Price Change over the period is " + WriteVal(EndValue(SDPerCent))
+ "\nMonthly Std Dev of % Price Change over the period is " +
WriteVal(EndValue(SDPerCent*(21)^.5));
/*NumColumns = 2;
Column0 = PerChange;
Column1 = SD;
Column0Name = "% Price";
Column1Name = "P StD";*/
AddColumn(7,"7");
AddColumn( SDPerCent, "SDPerCent" );
AddColumn(PerChange,"% Change");
AddColumn(SD,"SD");
