Technical Notes 
Modal dialog boxes are initiated with the ABAP/4 keyword CALL SCREEN STARTING AT X ENDING AT Y. To do this, the flag for the modal dialog box has to be set in the screen attributes in the Screen Painter.
Titles and function keys are defined in the Menu Painter. In the program, the title must be set with SET TITLEBAR and the status with SET PF-STATUS. The title is then automatically centered in the title bar of the window. The title is not underlined. In the Screen Painter, the title bar is not to be taken into account during the definition of the window. On output, the dialog box is automatically extended by one line.
The
F12
functionality (
Cancel) has to be programmed by the developer himself.
The pushbuttons are defined as function keys in the Menu Painter. The
ENTER
key can and must be reserved (function key <00>, any function code). The function key
F1
must not be reserved. The text in pushbuttons is followed by an ellipsis (...) if it initiates another dialog box. Programmers have to set the ellipsis themselves.
