SQL not parsed correctly Why is meant by SQL Statements Larger than 32KB?

Question

I execute the following code
     begin
          dbms_output.put_line('b4 Constructing query 2');
          v_retail_rate_query_a:='select *
          from Rate R
          where rate_id=:v_RateID
          and service_id=:p_ServiceID
AND SUBSTR(R.Area_Code, 1, LEAST(LENGTH(:v_Orig_Number), LENGTH(R.Area_Code))) = SUBSTR(:v_Orig_Number, 1, LEAST(LENGTH(:v_Orig_Number), LENGTH(R.Area_Code)))
AND LENGTH(R.Area_Code) <= LENGTH(:v_Orig_Number)
          v_query_a_length:=length(v_retail_rate_query_a);
          dbms_output.put_line('v_retail_rate_query_a ' || v_retail_rate_query_a || ' |');
          dbms_output.put_line('v_query_a_length ' || v_query_a_length || ' |');
     exception
          when others then
          :v_ErrNumber:=-1800;
     end;
But the statement is not parsed correctly why is this so? with reference to http://download-west.oracle.com/docs/cd/B10501_01/appdev.920/a96590/adg09dyn.htm#26624
32k /8 would have give me at most 4000 characters. the query certainly does not have 4000 characters.
Anybody could enlighten me with the reason why oracle could not parse my query? Is there a way to insert '\n' in Pl/SQL?
thanks!

You do in your select statement length(r.area_code) <= length(:v_orig_number), so least(length(:v_orig_number),length(area_code)) will always return
length(r.area_code).
substr(r.area_code,1,least(length(:v_orig_number),length(r.area_code))) will return area_code because substr(r.area_code,1,length(r.area_code)) will return r.area_code.
SUBSTR(:v_Orig_Number, 1, LEAST(LENGTH(:v_Orig_Number), LENGTH(R.Area_Code))) will return
SUBSTR(:v_Orig_Number, 1,length(r.area_code)).
I believe you can use select statement
select *
from rate
where rate_id = cp_rate_id
and service_id = cp_service_id
and cp_orig_number like area_code||'%';
Use this PL/SQL code.
set serveroutput on
declare
cursor c_rats( cp_rate_id     in rate.rate_id%type
             , cp_service_id  in rate.service_id%type
             , cp_orig_number in varchar2)
       is
       select *
       from   rate
       where  rate_id           = cp_rate_id
       and    service_id        = cp_service_id
       and    cp_orig_number like area_code||'%';
begin
  for r_rats in c_rats(1,2,'ABCDEFG') loop
    dbms_output.put_line(r_rats.rate_id);
  end loop;   
end;
/Here I used rate_id = 1, service_id = 2 and orig_number = 'ABCDEF'.
