Locking rows in a Procedure NOWAIT?

Question

I'm trying to create a procedure with a NOWAIT statement in it, but everytime I add my NOWAIT statement it gives me Warning: Procedure created with compilation errors. When I take the statement out it works fine? Can anyone help me with this?
SET SERVEROUTPUT ON
SET VERIFY OFF
CREATE OR REPLACE PROCEDURE upd_sal
(p_jobid IN jobs.job_id%TYPE,
p_minsal IN jobs.min_salary%TYPE,
p_maxsal IN jobs.max_salary%TYPE)
IS
e_invalid_maxsal EXCEPTION;
e_rowlocked EXCEPTION;
PRAGMA EXCEPTION_INIT
(e_rowlocked, -0054);
BEGIN
UPDATE jobs
SET job_id = p_jobid, min_salary = p_minsal, max_salary = p_maxsal
WHERE job_id = p_jobid
FOR UPDATE NOWAIT;
IF SQL%ROWCOUNT = 0 THEN RAISE NO_DATA_FOUND;
ELSIF p_maxsal < p_minsal THEN
RAISE e_invalid_maxsal;
END IF;
EXCEPTION
WHEN e_invalid_maxsal THEN
DBMS_OUTPUT.PUT_LINE ('MAX SAL SHOULD BE > MIN SAL');
WHEN NO_DATA_FOUND THEN
DBMS_OUTPUT.PUT_LINE ('NO_DATA_FOUND');
WHEN e_rowlocked THEN
DBMS_OUTPUT.PUT_LINE ('Job information is currently locked, try later.');
END upd_sal;
