Modified Data Tag(MDT)is one bit attribute character.
If it is ON(1)means,it indicates that it is modified by
terminal operator.
FRSET is Field Reset is used in the CNTL parameters of the
map definition (DFHMDI) or mapset definition(DFHMSD).If
CNTL=FRSET,when the map or mapset is sent to the
terminal,MDT will reset to '0' indicating it is not
modified by terminal operator.
FSET is Field set is used in the ATTRB parameters of the
field definition of the BMS maps(DFHMDF).If FSET is
specified in ATTRB parameter of the DFHMDF macro for a
field,when the map is sent to the terminal,MDT will be set
to '1' for the field regardless of whether the field has
been modified by the terminal user.
Following explanation will help you to understand better.
You cannnot assume the terminal user will always type some
data into all unprotected fields.He/she might forget to
type some required fields,or intentionally skip certain
fields.In such cases the program might not get data in the
fields as the program expects.
In order to prevent the troublesome situation, We use the
concept of FSET and FRSET.
