QPRINT authorities

        We have a system running V4R5 on which the base app we run gives all 
users
*JOBCTL spec authority.  All users use QPRINT as their default printer, and
dump a good bit there for retrieval via OPSNAV.  I am dealing with users
going in thru WRKOUTQ to the QPRINT que and reading, deleting, or whatever,
other users spool files. 

        It is my understanding that setting the DSPDTA to "owner" and OPR to 
"no"
for the QPRINT que will prevent this, however I am not clear about how to
keep the sysopr, who logs on under her own name, from being locked out as well.

        Any suggestions or comments would be GREATLY appreciated.

Thanks
Terry
