Create different log file with different schema by spool

Question

Hello,
I want to know a way to create a different log file depend on different schema
I have two schema on same db server
1) schema kennam/*****/kennam
2) schema koonhey/*****/koonhey
by a way, I want to create a different log file name e.g. kennam.log / koonhey.log on such two schema...
I always run @showbalance; to run showbalance.sql to create that report..
I hope you understand what I talking about (english is not my native language........), anyone could help?
showbalancelog.sql
spool c:\log.log+
spool c:\log.log
select to_char(sysdate,'dd-mm-yyyy hh:mi:ss') from dual;
column com_name format a20;
select cus.tid, cus.com_name com_name, cus.com_balance,
NVL((select sum(invoice_total) from invoice where com_id=cus.tid),0) sum_invoice,
NVL((select sum(cheque_amount) from income where com_id=cus.tid),0) sum_income,
cus.com_balance -
NVL((select sum(invoice_total) from invoice where com_id=cus.tid),0) +
NVL((select sum(cheque_amount) from income where com_id=cus.tid),0) total_balance
from customers cus
order by cus.tid;
spool off

okey I solved on this way, is anyone know another simpler way?
be simpler part
variable vspoolfile varchar2(20)
declare
username varchar2(20);
spoolfile varchar2(50);
begin
select 'c:\' || user || '.log' into spoolfile from dual;
-- spoolfile := 'c:\' || username || '.log';
:vspoolfile := spoolfile;
-- dbms_output.PUT_LINE(spoolfile);
end;
-- print :vspoolfile;
column spoolfilecol new_value definespoolfile noprint
select :vspoolfile spoolfilecol from dual;full content of my showbalancelog.sql file
variable vspoolfile varchar2(20)
declare
username varchar2(20);
spoolfile varchar2(50);
begin
select 'c:\' || user || '.log' into spoolfile from dual;

:vspoolfile := spoolfile;
-- dbms_output.PUT_LINE(spoolfile);
end;
-- print :vspoolfile;
column spoolfilecol new_value definespoolfile noprint
select :vspoolfile spoolfilecol from dual;
spool &definespoolfile;
column com_name format a20;
select cus.tid, cus.com_name com_name, cus.com_balance,
NVL((select sum(invoice_total) from invoice where com_id=cus.tid),0) sum_invoice,
NVL((select sum(cheque_amount) from income where com_id=cus.tid),0) sum_income,
cus.com_balance -
NVL((select sum(invoice_total) from invoice where com_id=cus.tid),0) +
NVL((select sum(cheque_amount) from income where com_id=cus.tid),0) total_balance
from customers cus
order by cus.tid;
