graying out within dcl

Does anybody have a simple example of lisp code that controls a dcl file that will dynamically gray out and return to active elements based on another radio button within the same dcl file.

i.e. On one row I have the user choose if they want an offset and on the next line what that offset distance would be, but I would like to change the code so that if they choose no offset the offset distance is grayed out and not available for them to edit. Don

(defun next ()
(setq pagenum (1+ pagenum))
(if (< pagenum pages)
(mode_tile "next" 0)
(mode_tile "next" 1)
); end if
(mode_tile "prev" 0)
(fill_slides dwgs (* (1- pagenum) 8))
); end function
;;
(defun prev ()
(setq pagenum (1- pagenum))
(if (> pagenum 1)
(mode_tile "prev" 0)
(mode_tile "prev" 1)
); end if
(mode_tile "next" 0)
(fill_slides dwgs (* (1- pagenum) 8))
); end function

Save the space, why even grayout the edit_box.

(if (> (distof $value_of_edit_box) 0)
(progn
(don't_offset)
(do_what_ever)
)
)
