Sounds like basic PL/SQL stuff.
What problem are you experiencing?
Are you looking for something like this?
create or replace procedure check_emp (p_empno in number, p_result out boolean) is
  dummy  pls_integer;
begin
  select 1
  into dummy
  from scott.emp
  where empno = p_empno;
  p_result := true;
exception
  when no_data_found then
    p_result := false;
end;
SQL> declare
  2    emp_exists  boolean;
  3  begin
  4    check_emp(7839, emp_exists);
  5    if emp_exists then
  6      dbms_output.put_line('Employee exists');
  7    else
  8      dbms_output.put_line('Employee does not exist');
  9    end if;
10  end;
11  /
Employee exists
