Dbms_output.put_line not displaying anything

Question

I am running the below code (ssn_run.sql) using sqlplus 10.2.0.1.0 on my windows XP professional client PC.
The database is a Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bit running on Solaris
I cracked my head for about one hour but couldn't figure out this :
accept input_ssn prompt 'Enter SSN :'
set feedback on
set serveroutput on
set echo on
set term on
set heading on
set pagesize 0
set linesize 10000
set verify on
undefne sdate input_ssn
col sdate new_value sdate
col input_ssn new_value input_ssn
select to_char(sysdate,'YYYYMMDD') sdate from dual;
spool C:\PERSON_DATA_&&sdate._&&input_ssn..TXT
select 'REPORT GENERATED ON : '||SYSDATE FROM DUAL;
begin
select personid into v_personid from person where SIN = '&&input_ssn';
INSERT INTO PERSON_OLD
(PERSONID, TITLE, FNAME, MNAME, LNAME, ACFM, SIN, UNAME, AKANAME, DCFM,
IROWID, SUFFIX, PTYPE, OLD_SSN)
SELECT PERSONID, TITLE, FNAME, MNAME, LNAME, ACFM, SIN, UNAME,
AKANAME, SIN FROM PERSON WHERE SIN = '&&input_ssn';
INSERT INTO MEMBER_OLD
(CLNT, MKEY, PERSONID, MEMNO, OLD_MEMNO)
SELECT CLNT, MKEY, PERSONID, MEMNO,MEMNO
FROM MEMBER WHERE PERSONID IN(SELECT PERSONID FROM PERSON WHERE SIN = '&&input_ssn');
UPDATE PERSON SET FNAME = TRANSLATE(SIN,'0123456789','ACEGIKMOQS'),
LNAME = TRANSLATE(SIN,'0123456789','SQOMKIGECA'),
UNAME = TRANSLATE(SIN,'0123456789','ACEGIKMOQS')||' '||TRANSLATE(SIN,'0123456789','SQOMKIGECA'),
AKANAME=NULL WHERE SIN = '&&input_ssn';
UPDATE MEMBER SET MEMNO = MKEY WHERE PERSONID IN(SELECT PERSONID FROM PERSON WHERE SIN = '&&input_ssn');
for i in(select personid person_other from person_relation where relpersonid in(select personid from
person where PERSONID = v_personid))
loop
dbms_output.put_line('i.person_other is : '||i.person_other);
UPDATE MEMBER SET MEMNO = MKEY WHERE PERSONID = i.person_other;
end loop;
EXCEPTION
WHEN OTHERS THEN
     ecode := SQLCODE;
     emesg := SQLERRM;
     dbms_output.put_line('Error while data scrubbing: Error code is : ' || ' - ' || ecode);
     dbms_output.put_line('Error message is :' || ' - ' || emesg);
end;
spool off;
set term on
set feedback on
set HEADING on
set verify on
--End of code
The SELECT statement that comes in the for loop should return data as v_personid has a value. (I tested this by a select statement)
However, I am just not able to display the line which comes in the inner loop :
dbms_output.put_line('i.person_other is : '||i.person_other);
The result of this dbms output put_line neither shows up on the screen, nor it gets written to the spool file...I am stumped with this...
The other dbms_output put_lines that display error displays okay, but not the one in the inner loop.... Can someone help me out if you see any obvious issues here........
Also my UPDATE MEMBER statement inside the for loop doesn't do anything whereas it was supposed to update a row !!
Thanks

You could display the number the query return by adding;
v_count number;After you assign v_personid;
dbms_output.put_line('v_personid  is : '||v_personid );
(select count(*)
into v_count
from person_relation
where relpersonid in(
   select personid
   from person
   where PERSONID = v_personid)).
dbms_output.put_line('v_count  is : '||v_count );
