>>        I've got some date fields on display record defined as numeric
length 8,0.  ... snip ... 
they are displaying the new values(8-Digit dates). If there is any error
in any of the field then the values even in the other date fields aren't
get updated on the screen(It displays only the 6-Digits for all). 
       If I've got to update the values in the date fields in display
which aren't having errors what am I supposed to do. <<

You need to write the new values (WRITE op code) before you turn on any
ERRMSG keywords. Create an array of bytes corresponding to the error
message indicators and turn them on when an error is detected. Also turn
on an ERROR flag to condition things. After all validations, check the
ERROR flag. If it's on, WRITE the display  with updated values and
(using - as someone else pointed out - the PUTOVR and OVRDTA keywords if
bandwidth is a consideration) then move the internal flags to the ERRMSG
indicators, and EXFMT the display to display the errors. It seems a
little silly to need to jump through hoops to display a simple error
message, but that's the way it is...
