title: Trying to create stored procedure in Oracle SQL
body: <p>I'm trying to create a procedure in Oracle. I want to be able to call on the procedure with a variable input and have a statement read. I am in the process of learning Oracle SQL, so I'm not sure where I'm going wrong.</p>
  <p>This is my code:</p>
  <pre><code>create or replace procedure gradeCheck(grade char(1))
  
  Begin 
    Case
      When grade = 'A' then DBMS_OUTPUT.PUT_LINE('Great Work')
      else DBMS_OUTPUT.PUT_LINE('Not great work')
    end case;
  end gradeCheck;
  /
  
  Begin 
    gradeCheck(A);
  end;
  /
  </code></pre>
  <p>I want the input to be 'A' (the grade assignment) and to get the text output. I am getting a message that the <code>GRADECHECK</code> procedure is being compiled. But it won't let me call it with an input.</p>
