The file also contains a 20 character customer name and a balance due. 2) A transaction file that contains records of each transaction. This file is also in ascending order by customer number There should be more than one transaction record per master record. Each related group of data in a file is called a record.

CUSTOMER NAME CUSTOMER NUMBER PREVIOUS BALANCE $XXXXX TRANSACTION # TRANSACTION # TRANSACTION # TRANSACTION # ITEM ORDERED ITEM ORDERED PAYMENT TEM ORDERED $ORDER AMOUNT $ ORDER AMOUNT S PAYMENT AMOUNT $ ORDER AMOUNT BALANCE DUE $XXX.xx Don't forget, payments reduce the balance and orders increase it.
