The list level can be specified with the addition •, where idx expects a data object, which contains the list index, of type i. The value of idx must be greater than or equal to 0. If the addition • is not specified, the list level 0 (the basic list itself) is selected when the basic list is created and the list level at which the event was raised (sy-listi) is selected when a list event is processed. The list page can be specified either with PAGE page or with CURRENT PAGE. page expects a data object of the type i that contains the page number of an existing page of the list level. No line is selected if no line is found for the specified values in line, idx and page. CURRENT PAGE indicates the topmost displayed page of the list, on which the last list event has taken place. No line is selected while creating the basic list. If no addition is specified for the page, the current page (sy-pagno) is selected when the basic list is created, and the page on which the event was raised (sy-cpage) is selected during the processing of a list event. • CURRENT READ LINE

Example ABAP Coding
This example reads all lines of the basic list after selecting a line. The content of the checkbox is assigned to the output data object flag. A target field wa with length 10 is used for the date, since this is the length of the output area and contains separators. If an assignment was made to the output field date, the area length would be reduced. The selected data is displayed in the details list. ABEXA 00522 ABAP_EXAMPLE_END
