What is an MDT (Modified Data Tag) - it's meaning and use?
Answer Posted / sheeja rajesh
Meaning of MDT:
--------------
MDT is modified data tag, a 1 bit of the attribute
character.
It can be defined for a field in the screen.
If this bit is OFF (0), then it means that this field has
not been modified by the terminal operator else if it is ON
(1), then it means that this field has been modified.
Only if MDT is ON, the data of the field is sent to the
application program.
So BMS mapping to the corresponding application programs
can be done using MDT field.
USE of MDT:
1. reduces amount of data traffic in the communication line.
2. improves peformance
