My code is similar to the following:
SELECTION-SCREEN BEGIN OF BLOCK out WITH FRAME TITLE text-s01.
SELECTION-SCREEN BEGIN OF LINE.
PARAMETERS: p_filchk AS CHECKBOX.
SELECTION-SCREEN COMMENT 4(17) text-s02 FOR FIELD p_filchk.
SELECTION-SCREEN POSITION POS_LOW.
PARAMETERS: p_file LIKE rlgrap-filename.
SELECTION-SCREEN END OF LINE.
SELECTION-SCREEN END OF BLOCK out.
Problem: I want to add text corresponding to the checkbox created(p_filchk). I tried with "Go To->Text Elements -> Selection Text" and gave text for p_filchk, but it still does not display on the screen. Could anyone please tell me how to go about it?
