execute script from sqlplus command line

Hi,

I execute sqlplus myuser/mypassword@myhost @c:\temp\batchtest.sql

In the batchtest.sql, I have this :

spool C:\Temp\test1.txt
@C:\Temp\testphm.sql
spool off
exit


In the testphm.sql, I have this :

DECLARE
tbl_exist PLS_INTEGER;
BEGIN
SELECT COUNT(*) INTO tbl_exist FROM user_tables WHERE table_name = 'ADP';
END;

When I execute the prompt is like this :

Connected to:
Oracle9i Release 9.2.0.8.0 - Production
JServer Release 9.2.0.8.0 - Production

  8

It's stop with this "8" which seems the last line number of the script...

Any idea ?

TIA.
