FSET sets the MDT value to?
A
Correct answer
Explanation
FSET (Field Set) in CICS/VSAM sets the MDT (Modified Data Tag) value to 1. The MDT flag indicates whether a field has been modified by the user. When MDT=1, the field data is transmitted to the program even if the user didn't change it. FSET=1 ensures the field is always included in the data stream.
