RE: OPNQRYF a flat file?

Buck,

I was trying to avoid copying the flat file to an externally described work
file.  I need to investigate what the typical record counts of this file will
be to determine whether the time to do the copy just so it can be externally
described to be copied again is a show-stopper or not.  Obviously, if the
typical record count is low, then I'll just do the copy.

But even if I end up doing that, I'll still be curious about my original
question.  There's just *gotta* be a way to use OPNQRYF to do this, don't ya
think?

And, yes, I thought for a split second of using FMTDTA, although I have zero
experience with it.  So, please educate me with your examples.

I have never tried it, but your MAPFLD approach is the way to do it.  If you
are forced to use OPNQRYF, copy the flat file to a work file that is
externally described and do your compares against that.  If alternate
solutions are allowed, look at FMTDTA.  FMTDTA can do record selection and
sorting.  I can provide examples if you wish.
