CPD5237 in V5R1 printer file

I found an old thread from 2002 that talked about the problem I'm
having, but I'm not entirely sure of the solution.  I'm making a
modification to an RPG program, so I converted from RPG III to RPG IV
and decided to move to an external printer file.  The mod is a major
output change, so it seemed like a good idea at the time.  I haven't had
much experience with printer files, so I've been learning quite a bit.
It seems strange to define all of my fields again, and arrays can't be used.

I got through that part, but I have one line that could have the same
field in three different places based on other factors.  I coded it just
like from the O spec with conditioning indicators and the same field in
multiple locations.  That is where I get the CPD5237 telling me the
field has already been used in the record.  What?  Why on earth can't I
use the same field more than once?  I can imagine many uses for such a
feature.

Is there a quick fix that I misunderstood?  I don't want to have to
define new fields, because I would then have to change the RPG to
populate those fields (or create a DS to overlay them).

Thanks all!

(P.S.  The OS will be upgraded "RSN" but this needs to be resolved
before that date.)
