User queues are just a different designation of data queues. The
difference is internal in the object type flag of the object itself.

The primary difference is that you need to write your own access
(originally in MI, and now through API's) routines to put entries on,
and take entries from the user queues. The user queues are not
accessable with the QSNDDTAQ and QRCVDTAQ OPM program interfaces.

I generally use the user queues instead of data queues whenever I am
working in the ILE environment, but I have already written the access
routines and put them in a service program, so they are just as handy to
me as the QSNDDTAQ and QRCVDTAQ OPM program interfaces are to anyone
else.
