  4. The DATA step stops executing at the point of the error and the resulting DATA set contains observations up to that point

Show answer
Correct Option: B

AI Explanation

To answer this question, we need to understand what happens when SAS encounters a data error in a DATA step.

Option A) The DATA step stops executing at the point of the error and no SAS dataset is created - This option is incorrect. When SAS encounters a data error in a DATA step, it does not necessarily stop executing at the point of the error. Instead, it continues to execute unless specified otherwise.

Option B) A note is written to the SAS log explaining the error and the DATA step continues to execute - This option is correct. When SAS encounters a data error in a DATA step, it writes a note to the SAS log explaining the error and continues to execute the remaining part of the DATA step. This allows SAS to process as much of the data as possible, even if there are errors.

Option C) A note appears in the SAS log that the incorrect data record was saved to a separate SAS file for further examination - This option is incorrect. SAS does not automatically save the incorrect data record to a separate SAS file. However, you can manually code SAS statements to capture and save problematic records for further examination.

Option D) The DATA step stops executing at the point of the error and the resulting DATA set contains observations up to that point - This option is incorrect. As mentioned earlier, SAS does not necessarily stop executing at the point of the error. It continues to execute the remaining part of the DATA step.

Therefore, the correct answer is B. When SAS encounters a data error in a DATA step, a note is written to the SAS log explaining the error, and the DATA step continues to execute.
