    PID NUMBER)
AS
  VCOUNT NUMBER;

  SELECT COUNT(*) INTO VCOUNT FROM EMP WHERE EMPNO=PID;
  IF (VCOUNT=1) THEN
    RETURN 1;

Hi,
When a procedure encounters a RETURN statement, it Returns the control, back to the calling program. In the below example, P1 is calling P2. When P2 encounters a RETURN statement, control is passed back to P1 procedure and "Out of p2 procedure" message is printed as per below example.
Note: No further execution happens in P2 procedure when return is encountered.
create or replace procedure P1
as
Begin
p2;
dbms_output.put_line('Out of the p2 procudure");
end;
create or replace procedure P2
as
begin
dbms_output.put_line('calculation 1");.......
return;
dbms_output.put_line('calculation 2");
end;
{code}
