This is a tape-based master-transaction program segment. Assume the files are sorted into ascending sequence by key fields. Transactions may add, delete, or update master file records. Referring to statement #0350, what error, if any, has been detected?
Choice 1
There is no corresponding transaction record for the master record being processed following the initial read.
Choice 2
The master file is out of sequence.
Choice 3
A logic error has occurred.
Choice 4
The master record to be deleted does not exist.
Choice 5
The transaction file is out of sequence.
Can anyone please tell me which one is correct? |

| No. The idea of interview questions is that you tell us what you think, and we help you from that point onwards. |

Please use BBCode (see FAQ) for readability. For example:
| Code: |
0100 INITIAL-READ.
0110 READ MASTER-FILE
0120 AT END MOVE 'Y' TO MASTER-EOF-SW. |
