You might try something like:

create or replace procedure bit2byte (mybit_in in char) is x number;
y number;
a varchar2(8);
b char;
begin
 x := ascii(mybit_in);
 for i in 1..8
 loop
  y := mod(x, 2);
  if y = 1 then
   x := x - y;
   b := '1';
  else
   b := '0';
  end if;
  a := b || a;
  dbms_output.put_line(b);
  x := x / 2;
 end loop;
 dbms_output.put_line (a);
end bit2byte;

set serveroutput on
execute bit2byte('');
