Can I create a non-logged perm. table in a logged DB?

I have Informix ODS 7.2. I'd like to be able to keep rows inserted into a permanent table even if the 'insert' is in an active transaction that was rolled back. The reason for this is that I'd like to log atomic actions performed in a complex stored procedure to my own log table, but if I need to rollback work performed in the stored procedure I still want to keep the rows inserted into my 'log' table. Too bad Informix doesn't have the ability to print to a file from a stored procedure and the 'SYSTEM' call is too expensive to use extensively. Does anyone have any tips? Thanks, Kyle
