Use the flowchart in Figure 13.12 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.
Master | 11, 15, 31, 84, 87, 99 |
Transaction | 11, 12, 31, 31, 15, 84, 99 |
Record number 99 in each file is used to indicate the logical end of the file.
Process these data, using the flowchart in Figure 13.12. 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).
