Marc,

It's a real good idea to move them down to the user portion of the library
list.  Unless you're real sure about what order they can be put in, I'd be
sure that they stayed in the same relative order, no matter which portion of
the list thy're on.

A change to the system library list takes effect immediately for all _new_
jobs, so you could change the library list and then ask  a few users to sign
on and test the system.  If the results were not favorable, you can quickly
change the library list back, and have those users sign off and on again.

BTW, if anyone questions you as to why you're risking this change, ask them
how they test new program changes?  <bg>

They're both needed by nearly ever job.  The System portion of the library
list is the proper place for them. (Though one could argue that *PUBLIC does
not not *CHANGE rights tot the library.  But that's another subject.)

The default library for user message queues on the CRTUSRPRF command is
QUSRSYS, it may also be the default library for the CRTOUTQ command.  This
is done so that every user can find every other user's message queue and out
queue (because it's on the system library list).  It's not a bad
arrangement, unless you try to maintain several systems from one master....
then you end up distributing a lot of things in QUSRSYS that never get used
on most systems.
