May anyone know what this line mean and give me a exact case on how it use.
I think cust_id and phone_num are two column names.
%let cust = %str(cust_id phone_num);
------------------------------------update---------------------------------------
Actually,I wanted to know STR statement usage and for this specific case which I could not find too much information in the doc..
The %LET statement creates a global macro variable with a value of the literal text within the parentheses. To display the value in the SAS log, submit this code:
%put &CUST;

If you want to learn about macro quoting , assuming you are sound in other facets of the language, SAS docs alone will help. Otherwise, please get this book
The topic of macro quoting is too complicated to explain in a forum post.
