While I won't swear to this, I believe I got around this years ago by doing
a write of the ctl record (not EXFMT or READ) and then everything in the
subfile was set correctly. I don't believe the "update" takes effect until
the ctl record is rewritten. However, that was many years ago and I might
be remembering wrong or something might have changed.

Subject: DSPATR(MDT) and SFLNXTCHG lost after read/update/read
Hi all,
I have some validations that need to make more than one pass of the subfile
data.
If the data is changed, I would like to keep the SFLNXTCHG and one of the
field's MDT set.
If I READC or CHAIN, the CHANGE indicators are set. If I UPDATE the
subfile, redisplay the data to the user, then read the same data, everything
is good.
If I READC or CHAIN, followed by UPDATE, then read the same data again
without first redisplaying the data to the user, the CHANGE indicators are
not set.
I'm guessing it has something to do with the buffers.
Does anyone know of a way to accomplish this?
Thank you.
Yours truly,
Glenn Gundermann
