I like to think of temp-files as no different than perm (except that
they disapear when logging off, and of course implicates some set of
rules for which domain is searched first), and I think MPE is doing a
good job in making it look like that. In this case it means that the
reason you can't reuse it is not because it's a temp-file, it's because
the way to reuse a file as an output-file for :LISTF is to use a
file-equation (don't ask me why.., I guess it's just the way :LISTF
works, and it might be argued that it means less risk of losing data).
In your example
      BEDROCK:(ZXKENB):LISTF @;temp
      BEDROCK:(ZXKENB):file temp,oldtemp
      BEDROCK:(ZXKENB):LISTF @;*temp
                               ^^
would work (note the '*' for dereferencing the file-equation).

I'm no expert on MPE file domains (and I have never touched PH or Quiz),
but the way I interpret your example is:

> : file mysub = mysub;temp

here you're not telling MPE that you have a temp-file, but rather that
when this file is closed, it should be *closed* as a temp-file

the same here, a wild guess could be that Quiz opens the file (in the
following) as a new or a perm file, and it's only while closing it that
MPE gets a chance to see it already exists a temp-file with the same
name. What you might want to try here (still in guess-mode) is something
like:
     : file mysub = mysub,oldtemp
as this specifies that the file is an existing temp-file. I don't think
you need to specify ';temp' as files like this usually are closed the
same way they're opened.

you should note though, that programs are free to open files the way
they want to (well, at least try to) so Quiz might have it's own idea on
how to use the file described.

hth (and that it didn't add to any confusion)

/per (I think temp-files are great!)
