Re: Getting the field attributes of a subfile record

OK everybody, please don't shoot, but I think we need to look at this a 
different
way.
(Disclaimer - Worked 60 hrs this week, plus selling a house, and house hunting,
so maybe
                     my brain is mush.)
Assumptions:
      Display attributes such as RI are "Option" and will not be returned when
the record is read, just as
            the a CA/CF Key indicator is a "Response" indicator and will not be
output. (Even with
            INDARA, which uses the same location in memory for a given 
indicator,
even the indicator
            is defined as both a Response and Option indicator). If you look at 
a
compiled RPG program,
            or the buffer layout for input & output on the DSPF listing, you 
will
see this.)
      If a subfile record is not read/rewritten, then a redisplay of the subfile
will
            have the same display attributes, if OVRATR PUTOVR, etc. are
correctly specified.
Problem.
      Record is in error, or RI would not be on in the first place. So if the
record is in error,
      it should be read and re-validated every time the subfile is processed. If
on the other hand,
      the RI is indicating a non-error condition, then the record should not be
read unless it is
      changed.

Solution.
       Use the SFLNXTCHG keyword., and use READC to only read the subfile 
records
that have
       changed. If a record fails validation, you can specify SFLNXTCHG on the
record, which
       will cause the record to appear to be changed, even if the user did not
modify it.

Well, did this make sense, or should I just go to bed.
