Why isn't this code working?

string varArray[];
int start()
  {
//----
   procPopulateArray();
   Alert(varArray[4]);   
   return(0);
  }
//+------------------------------------------------------------------+
void procPopulateArray()
{
   int varHandle = FileOpen("currency.txt",FILE_CSV|FILE_READ,'~');
   int varCountArray=0;
   while (varHandle>0 && !FileIsEnding(varHandle))   
   {
     string varSymbol = FileReadString(varHandle);
     varArray[varCountArray]=varSymbol;
     varCountArray++;
   }
   if (varHandle>0)   FileClose(varHandle);
   
}

In a previous thread (http://www.forexfactory.com/showthread.php?t=277732) I got the help I needed in reading in pairs from a file.

But now I need to assign those pairs to an array so that I can write data from all of the pairs into one file.

Right now, I'm just trying to get the pairs read from the text file into an array....
