I have a raw text file that is a database (1 record per row) - containing account numbers, dollar amounts, and other items.  I would like to update this Text File Database with data from the line 'above' if the account numbers are the same for a new field - sample below
incoming
account# Check# CheckAmount Ending Balance
123456    12345               27.54         5987.62
123654      8761               14.34           890.65
123654      8765               87.55           817.44
123654      8790              101.23          803.76
123654      8801              914.12              9.13-
