reading CLOB issues

I am trying to read back a CLOB but its breaking the records , can you please tell me what I am doing wrong or how to read the CLOB in original form ?

SQL> DECLARE
     lobloc CLOB;
     buffer VARCHAR2(32000);
     amount NUMBER := 3000;
     amount_in_buffer NUMBER;
     offset NUMBER := 1;
   BEGIN
     --Initialize buffer with data to be inserted
     SELECT html_file INTO lobloc  -- get LOB handle
       FROM test_clob
       WHERE id = 1001;
     dbms_lob.read(lobloc,amount,offset,buffer);
     --using length built-in function to find the length of the buffer
  2    3    4    5    6    7    8    9       amount_in_buffer := length(buffer);
     dbms_output.put_line(buffer);
     dbms_output.put_line(to_char(amount_in_buffer));
