Answer Posted / tprabhakarreddy
Before having the answer for SFLNXTCHG, understand about
the MDT tag.
Modified Data Tag:
1. It is 1 bit of the attribute charecter and Every subfile
record will have a MDT tag and it will seton when the
record is changed.
2. Readc will record all subfile records whcih have MDT = 1
and once Readc is performed on changed record MDT will made
off.
3. Hence When you performed READC for the second time on
the same record, which has changed before but not changed
second time, will not work.
SFLNXTCHG keuword:
For reading the subfile reading in second time, which has
changed before but not changed second time, we have to
force the MDT flag set to 1. This can be done using
SFLNXTCHG keyword.
