Pl/sql procedure in package with out parameter

Question

Hi all,
my need is to run procedure in package and return 0 or 1 as out parameter depending on data selection.
How do I return value?
My first guess is to use raise_application_error, but maybe some other decision can be found here.
Looking forward to see your reply.
Thanks ahead.

How do I return value? Assign the desired value to the OUT parameter.
My first guess is to use raise_application_error, but maybe some other decision can be found here. You can do it in an EXCEPTION handler, if that makes sense.
Here's an example:
CREATE OR REPLACE PROCEDURE     dept_comm
(     in_deptno     IN     scott.emp.deptno%TYPE     -- Department of interest
,     out_comm     OUT     scott.emp.comm%TYPE     -- Total comm in that department
,     out_flag     OUT     NUMBER               -- 0 means there were no rows in table, 1 means there were
AS
BEGIN
     SELECT     SUM (comm),     COUNT (*)
     INTO     out_comm,     out_flag     -- See note (1) below
     FROM     scott.emp
     WHERE     deptno     = in_deptno;
     IF  out_flag  > 0     -- 0 and 1 are the only possible values for out_flag
     THEN
         out_flag := 1;               -- See note (2) below
     END IF;
END     dept_comm;
/This shows out_flag getting set 2 different ways:
(1) in a SELECT ... INTO statement
(2) in a normal assignment statement
Any other way that you can use to assign a value to out_flag (such as passing it as an OUT argument to another procedure) would work as well.
