Call A Function

Question

CREATE OR REPLACE FUNCTION fn_easy1 RETURN VARCHAR2 IS
BEGIN
dbms_output.put_line('this is a simple function');
RETURN 'This is a simple function';
END fn_easy1;
I have this function, how can i call it in oracle??
like this its not working call fn_easy1();
i dont want to do it via select, select fn_easy1() from anything; works.. but i want to call it without the select thingy.

Answer 1

CREATE OR REPLACE FUNCTION inout_fn (outparm IN OUT VARCHAR2)
RETURN VARCHAR2 IS
BEGIN
outparm := 'Coming out';
RETURN 'return param';
END inout_fn;
SET serveroutput ON
DECLARE
retval VARCHAR2(20);
ioval VARCHAR2(20) := 'Going in';
BEGIN
DBMS_OUTPUT.put_line('In: ' || ioval);
retval := inout_fn(ioval);
DBMS_OUTPUT.put_line('Out: ' || ioval);
DBMS_OUTPUT.put_line('Return: ' || retval);
END;
call inout_fn('Going on');
How can I use the call keyword to call a function?
I get an error of
ORA-06576: not a valid function or procedure name
