EG in 
CREATE OR REPLACE Procedure UpdateCourse
   ( name_in IN varchar2 )
   
IS
   cnumber number;

   cursor c1 is
   SELECT course_number
    FROM courses_tbl
    WHERE course_name = name_in;

BEGIN

   open c1;
   fetch c1 into cnumber;

   if c1%notfound then
      cnumber := 9999;
   end if;
   
   INSERT INTO student_courses
   ( course_name,
     course_number )
   VALUES
   ( name_in,
     cnumber );

   commit;

   close c1;

EXCEPTION
WHEN OTHERS THEN
   raise_application_error(-20001,'An error was encountered - '||SQLCODE||' -ERROR- '||SQLERRM);
END;

It would be nice to have basic support for 
- variables and types (varchar,%TYPE...)
- refactoring for variables
- STRG-space support for variables and types
