I$\text{'}$m trying to use PROC IMPORT to read in some data delimited with $"$@$.$ Will I need a DELIMITER statement?

Yes, we'll need a statement that has DELIMITER $=\text{'}$@$\text{'},$ and DBMS $=$ DLM$.$

Yes, we'll need a statement that has DELIMITER $=\text{'}$@$\text{'},$ but there's no requirement that DBMS $=$ DLM$.$

No$,$ we don't need a DELIMITER statement. We need to include DELIMITER $=\text{'}$@$\text{'}$ as an option within the PROC IMPORT statement.

No$,$ we can use DBMS $=$ CSV$.$
