MDT is a internal indicator.It is used when we are using
SFLNXTCHG in SFL.MDT indicator default in on mode.
breifly when we are using readc for read changed
records.MDT is internally on for every record .If retreive
the record once MDT is going to be off.for that purpose we
used SFLNXTCHG keyword to seton.

Answer / kirthika mohan

MDT -Modified Data Type is an indicator defined
internally. When we use SFTNXTCHG this indicator comes
into picture. Whenever there is a change in subfile
records, we read the changed record using keyword READC,
this indicator is automatically turned off.
