Because it's a string and AddColumn only works with arrays.
You are stuck with the numeric output. I don't know if you can add
string data to the number. I think not.

Subject: [amibroker] DateTime() in Exploration Column
Hi,
I'm running the following AFL to Explore the Range of 7/1/2006
through 7/14/2006 against a single symbol, IBM-5159:
SetOption("NoDefaultColumns",True);
Filter = True;
AddColumn(DateTime(),"Date / Time",formatDateTime);
AddTextColumn(Name(),"Symbol");
AddTextColumn(NumToStr(DateTime(),formatDateTime)+"_"+Name(),"Key");
The Exploration output is:
Date / Time Symbol Key
7/3/2006 IBM-5159 7/14/2006_IBM-5159
7/5/2006 IBM-5159 7/14/2006_IBM-5159
7/6/2006 IBM-5159 7/14/2006_IBM-5159
7/7/2006 IBM-5159 7/14/2006_IBM-5159
7/10/2006 IBM-5159 7/14/2006_IBM-5159
7/11/2006 IBM-5159 7/14/2006_IBM-5159
7/12/2006 IBM-5159 7/14/2006_IBM-5159
7/13/2006 IBM-5159 7/14/2006_IBM-5159
7/14/2006 IBM-5159 7/14/2006_IBM-5159
Why doesn't the DateTime() portion of the "Key" column vary as it
does in the first column, "Date / Time"?
What alternative should I use to generate a unique key that combines
date and symbol in an Exploration?
Thanks,
