My apology for being a bit unclear on the requirements..

I'm better with examples: I need to process multiple log files containing thousands of 'DOW' related records each. (same data structure as shown in my original post). My goal is to determine if any record in the new log files contain a value in the 7th element that is greater than the current maximum value stored in the 'DOW' record of an index maximum CSV file. That CSV file will contain only 1 record per financial index. (ie DOW, SP500)
