Thanks guys, I may have been too general. The only way I know to declare a procedure requires the inclusion of a parameter or signature such as the "param" in "PROCEDURE my_proc(parar in varchar2) as ...." . This is how/why it is "declared". Is there a way not to include a parameter or signature ? If it is essential what makes Oracle recognize that it has been used ? I've tried things like some useless "if" statement
( if param = param then
  param = null;
 end if;) to no avail.

One thought is that I use PL/SQL developer and this my relate to the tool and not PL/SQL at all . Any thoughts on rhis ?
