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;

The topic of macro quoting is too complicated to explain in a forum post.
You have been recommended a good book. See also this documentation:
