> 1. How can find the creator of this file?

  LISTFILE Onnnnnn.out.hpspool,-3

MPE filenames, like above, are not case sensitive.  You could also use:
  LISTFILE /HPSPOOL/OUT/Onnnnnnn,-3
and the name is now case sensitive. Notice MPE account and MPE group
names are uppercase here.

Finally you could run the POSIX shell (sh from the CI prompt) and then
enter:
  ls -l /HPSPOOL/OUT/Onnnnn

All of the above examples will reveal the file's creator.

The HPSPOOL account grants read access to ANY.  See the CI command
LISTACCT hpspool
The OUT.HPSPOOL group also grants read access to ANY. See LISTGROUP
out.hpspool
Individual files in OUT.HPSPOOL (same as in /HPSPOOL/OUT) restrict all
accesses to just the file's creator. See LISTFILE Onnnnn.out.hpspool,4

So if you are not a privileged user you cannot read someone else's
spoolfiles.  You need SM (system manager) capability to view an
arbitrary spoolfile.  SM is similar to Unix root user.  If you have PM
(privilege mode) capability there are ways to temporarily grant yourself
SM, read the file, and then remove SM.  This is not directly supported
by MPE but at least one 3rd party tool provides this feature.

From the CI entering HELP LISTFILE is a good start.  You may also want
to search docs.hp.com where I entered LISTFILE and found 407 matches.

There are several papers on our Jazz website
(http://jazz.external.hp.com/papers) along with lots of freeware.

Also, HELP SUMMARY onlineinfo  provides more links.  Plus this list,
hp3000-L, and HP's ITRC (itrc.hp.com) are great places to get MPE
questions answered.

Welcome to the group!
