I have utilized the following functions in I4GL to do what you describe: LET p_curr = arr_curr() - the arr_curr() function returns the row in the program array LET sc_curr = scr_line() - the scr_line() function returns the screen line in the screen array Once you know this info - you can manipulate the screen any way you want.
