Re: reading a sfl twice

When I have done this in the past, even with the sflnxtchg on, the second
time through I have to reposition the pointer or whatever it's called at
the beginning of the subfile.  Since setll is illegal for subfiles, I chain
with relative record one.  From then on readc works.  It's just like
reading a disk file.  Once you have read it, you have to reposition at the
beginning to read it again.

Is there a better way to do this?  I'd be interested to know.

set ind on for sflnxtchg & update sfl (not control). Then next readc of
same
sfl records will read all of them as changed
records. Good for read for errors & then read for update.
