hi experts,
id like to ask on how these codes work,
FORM entry USING return_code us_screen.
CLEAR retcode.
xscreen = us_screen.
PERFORM processing USING us_screen.
CASE retcode.
WHEN 0.
return_code = 0.
WHEN 3.
return_code = 3.
WHEN OTHERS.
return_code = 1.
ENDCASE.
ENDFORM. "entry
im having hard time to understand it, since its my first time encountering this codes.
also when i check the syntax an error prompt, that retcode is unknown,
do i have to declare it in data section?
thanks in advance.
