PL/SQL Newbie Question

I have a SELECT statement that returns 1 row in a procedure. I want to just set the variable that holds the column value to a space(' ') if the SELECT does not return a row (NO_DATA_FOUND) and go on with the logic. However when I get the NO_DATA_FOUND exception the procedure is exited. How do I prevent this?

Thanks for your help..
