I have a display file with 1 field having length 2 Alphanumeric. I want to know whether that field having value or not without any I/O operation on DSPF (i.e. without Hit ENTER or press Function keys). Since I need to auto pop up the window as soon (i.e. at second position/last position of that field when user inputs some value window get populated) entering value into field. Any other suggestions?
