prevent spooling from being stopped by spool off in secondary script being called

 I'm working on a table purge routine that is a sql script.  I start spooling a log at the beginning to check for errors.  In the middle of the routine I call another sql script that generates dynamic sql to rebuild the indexes on the table(s).  This routine spools a temp sql file to run.  The issue is this sub routine requires a spool off to do its thing.  Causing the spool logging in the main script to stop.

I'm looking for suggestions on how to best deal with this situation.  Thank you.
