Use the flowchart in Figure to solve this problem. Assume that the master file and the transaction file are composed of the record numbers shown below in the sequence given.

Record number 99 in each file is used to indicate the logical end of the file.
Process these data, using the flowchart in Figure. Indicate

a. Which master records are updated?
b. Which master records are not updated?
c. The disposition of each transaction record (i.e., posted to the master or an error condition).

Master Transaction 1. 15, 31, 84, 87.99 11, 12, 31, 31, 15. 84.99 1. Read Transaction Record (TR) 2. Read Master Record (MR) 3. Compare Record Kay Values 4. Write Master Record to Now Master File 5. End-of-File Test 6. Update and Write Master Record to New Master File 7. Write Error Notice to Error File 8. Read Transaction Record 9. End-of-Job Processing 2 TR (key)> MR (key) TR key) < MR (key) 3 TR key) = MR key) 5 No 8 6 9
