Answer Posted / manish_cics
The last bit in the attribute byte , the MDT( Modified data
Tag) , indicates whether the user has modified the data in
the field. to save transmission time , the terminal sends a
field to the CICS program only if its MDT is on. un
modified fields are not transmitted.
HOW TO SET/RESET MDT
there r three ways of setting and resetting MDT , as
follows:
1- when the terminal user modifies a field on a screen ,
MDT 'LL be set "1" (ON) automatically by the terminal
hardware.
2-if CNTL=FRSET is sepecified in the DFHMSD OR DFHMDI
macro , when the mapset or the map is sent to the
terminal , MDT will be reset to "0" ( OFF ie not modified )
for all fields of the mapset or the map , respectively.
3- further , if FSET is specified in the ATTRB parameter of
the DFHMDF macro for a field , when the map is sent to the
terminal , MDT will be set to "1" ( on , i.e. modified) for
the field , regardless of whether the field has been
modified by the terminal user.
the following technique shud be used:
. code CNTL=FRSET in DFHMSD or DFHMDI.
. CODE ATTRB=(FSET,..) IN all DFHMDF macros for the
fields , from which the application program expects to
receive data , regardless of whether they r input fields or
output fields .
