The data queue that is receiving the initial input will be "system wide"
because I will have a prestarted Java job out there waiting on that data
queue to pick them up and process them from any number of jobs.  So that can
be named DQIN for all intents and purposes.  The data queue the Java program
is responding to is the one that will need to be unique to the job.  

So that leaves me needing to create system wide uniquely named data queues.
Note though that it only has to be unique within the job because after it is
initially created (using the JOB_NUM as part of the name) I can reuse it and
not recreate it each time.  I can understand your concern about job numbers
going full circle, but I should be able to rely on the fact that the same
job number will never be active at the same time and based on that, as long
as I "initialize" the job number data queue at program startup time I should
be good to go.

This is where it would be nice to have a "destructor" routine in RPG that is
called when a program is ended because I am trying to figure out how to
cleanup the data queues unique to each job.  Sure I can code a routine that
the programming calling me can call when the user exits out of their
interactive app in a controlled fashion (i.e. hitting F3), but what is a
best method to cleanup when the user simply closes their 5250 emulation
window?

Thanks for your tangent Rob, it is helping me be sure of the direction I am
taking :-)

Going off on a tangent.  But if the data queue is used ONLY by that job, why
not create it in QTEMP and not worry about the data queue name?

If it is used by multiple jobs (and unless you a thread coding animal I
suspect it is) then you need to consider "truly unique".  Being as a data
queue program can run until the next IPL, and if you fire off enough jobs
between IPLs then your job number could be reused.  Maybe use UUID instead?
