How to Oracle stored procedure with output parameters

I did this:
var mycv1 sys_refcursor
var mycv2 sys_refcursor
var mycv3 sys_refcursor
var mycv4 sys_refcursor

exec  PROCEDURE GetCollectorInfo  (1,2,:mycv1,:mycv2,:mycv3,:mycv4);
print mycv1
print mycv2
print mycv3
print mycv4

error:
Usage: VAR[IABLE] [ <variable> [ NUMBER | CHAR | CHAR (n [CHAR|BYTE]) |
VARCHAR2 (n [CHAR|BYTE]) | NCHAR | NCHAR (n) |
NVARCHAR2 (n) | CLOB | NCLOB | REFCURSOR |
BINARY_FLOAT | BINARY_DOUBLE ] ]

When I did this:
var mycv1 refcursor
var mycv2 refcursor
var mycv3 refcursor
var mycv4 refcursor

exec  PROCEDURE GetCollectorInfo  (1,2,:mycv1,:mycv2,:mycv3,:mycv4);
print mycv1
print mycv2
print mycv3
print mycv4

No results

Bind Variable "MYCV4" is NOT DECLARED

Can you try this:
(enable DBMS output window)

DECLARE
  mycv1 sys_refcursor;
  mycv2 sys_refcursor;
  mycv3 sys_refcursor;
  mycv4 sys_refcursor;
BEGIN
  GetCollectorInfo(1,2,mycv1, mycv2, mycv3, mycv4);
  dbms_output.put_line(mycv1);
  dbms_output.put_line(mycv2);
  dbms_output.put_line(mycv3);
  dbms_output.put_line(mycv4);
END;

>>No results

I just provided 1 and 2 for v_organizationId and v_collectorId.

You'll need to provide correct numbers.

>>THis one works

That code as posted will not work.  In fact if you try it you should receive an error.

Below is an example showing this.  The example based on my post works.

The other one returns the error:

 dbms_output.put_line(mycv1);
  *
ERROR at line 5:
ORA-06550: line 5, column 3:
PLS-00306: wrong number or types of arguments in call to 'PUT_LINE'
ORA-06550: line 5, column 3:
PL/SQL: Statement ignored

drop table tab1 purge;
create table tab1(col1 char(1));

insert into tab1 values('a');
insert into tab1 values('b');
commit;

create or replace procedure myproc(p_outcur out sys_refcursor)
is
begin
	open p_outcur for select * from tab1;
end;
/

show errors

var mycv1 refcursor

exec  myproc  (:mycv1);
print mycv1



DECLARE
  mycv1 sys_refcursor;
BEGIN
  myproc(mycv1);
  dbms_output.put_line(mycv1);
END;
