example of READC & SFLNXTCHG

["Dan Bale" <dbale@xxxxxxxxx>]

Does anyone have example code or code for a short working demonstration
utilizing READC & SFLNXTCHG?  I have to retrofit an existing program to use
this, and can't remember the details on how this works.  For example, when I
write out the initial first page of empty subfile records, would I set the
indicator for SFLNXTCHG off?  I understand that the SFLNXTCHG indicator
should be set on when updating the subfile record if the record has an edit
error.

Do I have to specify an MDT attribute for the subfile?  Or does READC detect
changed subfile records without MDT attributes?

TFMs are woefully short on useful how-to information.
