Rakesh,
I am not following. It appears you are saying you already named some symbols as "SF_symbol1", "SF_symbol2". Is this correct? If so, your first line of code is looking for "SF_SF_symbolX", unless your current symbol = "symbolX" in which case I don't see the problem. You should be able to see the SF_NAME in the interpretation window since it is just a string. See if it's correct. -- Terry -----Original Message----- From: amibroker@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Rakesh Sahgal Sent: Monday, January 22, 2007 23:38 To: Amibroker Yahoogroup Subject: [amibroker] String manipulation I am in the process of setting up a database of single stock futures. I have allocated tickers/symbols to the stock futures on the basis of the symbols of the underlying along with the pre-fix "SF_" . If for instance I wish to write an AFL that will compare the close price of the underlying with the close price of the relevant SF how do I manipluate the strings to get foreign function to look up the correct SF ? I tried to make the code look up the futures price using the following code but it does not work,even though I tried to check it for accuracy by verifying the AFL syntax. It is obvious that my code is incorrect. Any pointers on how to correct this will be highly appreciated. TIA Rakesh SF_NAME="SF_"+"Name()"; SF_CLS=Foreign("SF_NAME","C",1);
