I think Joel was referring to the idea of "touching" every record in
the files to be copied, thus creating extra journal records. These
extra journal records would then be dumped to an output file.

Joel is looking for a method which reads the files to be copied and
writes directly to the output file, without using the journal for
intermediate storage. Gary's quickie read-update program was an
attempt to reduce the amount of RPG code to something as small and
simple as possible, since Joel expressed a desire to avoid RPG if
possible. The cost for this simplicity is that it uses journal space.
