Answer / ram
SFlNXTCHG is a subfile record format keyword.
If the SFLNXTCHG indicator is turned on and the subfile
record is written or updated the change flag will be forced
on so in the subsequent processing the READC will get that
record.
One use for this is so that the records can be edited for
errors and if no errors are found then they can be
processed. As the readc loop edits for errors it updates
each subfile record with the SFLNXTCHG indicator on and
that allow the update loop to use the READC to get the
records again.
If you perform read on the subfile, the internal indicator
MDT (modified data tag) is automatically set off by the
system. If you again perform read on the same records,
records won't be read. Because internal indicator MDT
would be off. Hence you should be explicitly set on the
MDT by SFLNXTCHG keyword.
Both are not same.
We Can use in Subfile.

Answer / reecha
1. when a read is performed on subfile , the MDT is turn
off .
2. So if again a read is done on subfile , it cannot sense
the change done on the subfile .
3.in order to sense the changed record use SFLNXTCHG
keyword by setting on the keyword & do an update in subfile
4. so now if agin u perform a read , the changed record
will be sensed.
