Store 837 Account Numbers For Comparison

Apr 30, 2015 at 7:21 PM
Is there an easy way to use this software to store account numbers from an 837 and look them up against account numbers in a .csv file?

I've tried to read through some of the provided source, hoping I could see how that particular field was being identified and use that to store it to an array or list, but I think it is going over my head.

Any ideas?
