MDT refers to the Modified Data Tag which is an attribute character of one-bit that allows on-screen modification of the field. In case if the user modified any field then MDT turns on automatically. The data is sent to the host program by terminal only if the MDT is on. There are two types of values in MDT which are 0 and 1. If the value is 0 then it means MDT is off and no modification is going on. If the value is 1 then it means that MDT is on and the terminal operator is modifying the field. Mdt is the source that helps you in controlling the data traffic.
