Remember,  If you use Data Queues associated with an output queue(when 
creating the outq designate a Data Queue) I believe an entry is placed 
on the Data Queue ONLY when a spool entry is placed there in the RDY  
status.   If a spool file is placed on the outq in a HLD status, for 
example,  a data queue entry is never made, and in your app (I think) 
you will never archive the spool file.  Watch out for this and 
other little nuances.   I kept my old polling program that I wrote 
because of this.

Hi Bob,

This is Erick from FORMation mg. I talked with you the other day on the
phone. I had found an archive article on data queues in NEWS/400 from
October 95 and will use this information as well as your information. 

Although not a current hot project, I would like to use a data queue
associated with an outqueue to trigger a batch program (our FORMS
engine). Currently, our forms engine poles the out queue at a predefined
interval of ten seconds. I really would like to redesign this using data
queues for the sake of efficiency.

Good talking with you the other day.
