3. From the COBOL Language Reference manual on 02 file status key:

This file status value applies only to indexed files with alternate keys
that allow duplicates.

Care to change your answer?

8. Your answer is wrong.

9. Don't know -- didn't test it.

12. Don't know -- didn't test it.

13. None of the answers are correct. LINKAGE SECTION is addressing in a called program that points to the data values passed from the calling program -- the storage comes from the calling program. It's not really temporary, it's not required unless data is being passed between the programs, it is NOT used by the calling program, and it could be used to display messages in the called program but that's not the main use.
