"PLS-00405: subquery not allowed in this context" Error


I am trying to compile my oracle stored proc, but the code keeps erroring on the following line:

elsif v_CODE NOT IN (Select CODE from CODE_TBL) then

I get an  "PLS-00405: subquery not allowed in this context" error.  If I run the embedded select statement in SQL+, it works fine, so I know the problem is not that the select statement is wrong

Is what I am trying to do not allowed?  If it's  not allowed, is there another way to do it?

Per the DOCS, you can't do this:

PLS-00405: subquery not allowed in this context
Cause: A subquery was used in an inappropriate context, such as: if (SELECT deptno FROM emp WHERE ... ) = 20 then ... Subqueries are allowed only in SQL statements.

Action: The same result can be obtained by using a temporary variable, as in: SELECT deptno INTO temp_var FROM emp WHERE ...; IF temp_var = 20 THEN ...

You will need to re-write the proc something like:
      myval      char(1) := 'X';
      isThere      char(1) ;

      select 'Y' into isThere from dual where myval not in (select dummy from dual);

      if myval <> 'Y' then
            dbms_output.put_line('Got it');
      end if;

            when no_data_found then
                  dbms_output.put_line('Did''t get it');
