You can call any selection screen of the main program, particularly the standard selection screen. Default setting is the display of the selection screen in the window of the preceding screen.

Notes
- The statement CALLSCREEN is not to be used to call selection screens, as otherwise the proper execution of the selection screen processing cannot be guaranteed.
- If the called selection screen is displayed in a dialog window, we recommend that you use the addition AS WINDOW when specifying the selection screen.
Addition 1
... STARTING AT col1 lin1 [ENDING AT col2 lin2]
Effect
With the addition STARTING AT, you create a modal dialog box and the selection screen is displayedin it. The upper left corner of the dialog box is determined by the values in col1 and lin1 for column and row. These values refer to the window with thePop-up-Level0. The lower right corner is either set automatically or can be specified in col2 and lin2after ENDING AT. For col1, lin1, col2 and lin2, data objects of thetype i are expected. The values of col1, lin1 should be smaller than col2, lin2; Otherwise the behavior will be undefined.
Addition 2
... USING SELECTION-SET variant
Effect
With the addition USING SELECTION-SET, you populate the parameters and selection criteria of the selection screen with theVariant,specified in variant . The transfer of the values to the respective data objects of the programtake place immediately before the event ATSELECTION-SCREEN OUTPUT. For variant, you have to specify acharacter-typedata object which at the execution of the statement contains the name of a variant of the main programin capital letters that was stored for the selection screen. If you specify a non-existing variant or a variant of another selection screen of the main program, then the addition is ignored.
