your first point, the variables are declared with po.pos_num%type. Of course this is also right for the other ones. So this should be safe.
Your second, i am not absolutely sure to get the right point. The database runs in NLS_CS we8iso8859p15 with language german_germany.
There is no conversion in this procedure, as far as i can see. There is no to_char, to_number or something similar.
