I think this is true only in very specific cricumstances, Reeve.  While I
haven't specifically tried it, I don't think you can write to the subfile
unless the display file is open.  And I do know that you cannot open a
"normal" display file in batch.  However, there is one possibility.  You may
be able to open the display file if you create it with DEV(*NONE).  However,
once you've gone so far as to create a display file just for the purposes of
storing and sorting temporary data, you're right: you should probably use an
array, or even a temporary file.
