Suppress blank line at top of spool file

Hi

I am using SQLPlus script to pull data from a table and spool to a text file. The app I need the spool file for expects certain data in the first line, which is gotten from the table by my script. However the spool file always begins with a blank line. Is there any way of suppressing this blank line? I have Oracle 9.2. The script is below.

Thanks


Script
---------
set serveroutput on;
set feedback off;
set linesize 300;
set heading off;
set pagesize 50000;
set echo off;
--set termout off;
spool spoolfile.txt;
select trim(text13)
from work_table
where code1 = 'UCNTL'
order by number1
;
spool off;
set echo on;
set heading on;
--set termout on;
set feedback on;
