TYPE-POOLS: vrm. "存放combobox内容的type pool
DATA: name TYPE vrm_id, "list box的名称
list TYPE vrm_values, "list box的值
value LIKE LINE OF list. "list box的结构
*定义checkbox，指定command，为了能够响应选择屏幕中值的改变
PARAMETERS: p_cb1 TYPE c AS CHECKBOX DEFAULT 'X' USER-COMMAND check,
p_cb2 TYPE c AS CHECKBOX DEFAULT 'X' USER-COMMAND check.
*定义listbox，必须指定visible length
PARAMETERS: p_list1(10) TYPE c AS LISTBOX
VISIBLE LENGTH 15 ,
p_list2(20) TYPE c AS LISTBOX
VISIBLE LENGTH 25 .
*开始执行
AT SELECTION-SCREEN OUTPUT .
*选择1而没有选择2
   IF p_cb1 = 'X' AND p_cb2 = ''.
*向listbox里面添加值
     REFRESH list .
    value-key = '1111111111' . "这个就是变量P_LIST的值
