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 .

how a data in physical and symbolic map gets treated? Since the physical map is much concerned about the screen alignment and the field positions, how the values entered in the field which has PICIN or PICOUT clause in Physical map gets treated? Does that mean datas recieved or sent to the physical map should be constant? How does the data in Symbolic map gets converted with 5suffix namely F,L,A,I and O. For example EMPNO is treated as EMPNOI, EMPNOO, EMPNOA, EMPNOL and EMPNOF. how does this happen in symbolic map. Please provide your inputs on the above and kindly correct me if I am wrong.
