Question about INPUT statement

Could someone explain why this question choose option B? (Confused about the "@"...)

Thanks!

The trailing '@' is a "line hold", which keeps the line and column pointer for the next input statement. At the end of the data step iteration, the line would advance automatically. A double '@@' would prevent even that.

Option B is incorrect. As you probably suspect, the answer should be A.

As fun as it is to use INPUT and INFILE to read raw data sets, I see that this has been posted in the "Certification" section rather than the generic "Programming" section of the community. Which leads me to believe that you are looking at this to prepare for certification. So I'll point out that INPUT/INFILE are no longer tested on any SAS exam. You can see the topics for our exams in the Exam Content Guide posted for each credential on www.sas.com/certify.

There is a second unconditional Input statement and previous conditional inputs do not end in @.

Thanks for your reminder!
Indeed, i'm preparing for the SAS base programming test. Probably the workbook i currently use is quite old... i was also confused when i saw this question as i noticed that the exam content guild does not have this point...
Anyways, it's clear now!
