                           := Button_OK or Button_Help;
       Default_Button     :        Message_Dialog_Buttons
                           := Button_OK;
       Help_Msg           :        String := "";
       Title              :        String := "";

                           := Justify_Center)
       return Message_Dialog_Buttons;

Display a message dialog box centered on the mouse.
This will create a dialog box containing the specified message. Dialog_Type indicates the purpose of the dialog. Buttons indicates which buttons should appear in the dialog. Help_Msg is the message displayed in a separate dialog box when the help button is pressed while the dialog is displayed. If Help_Msg is null, a dialog containing the message "No help available" will be displayed. In both cases, the dialog displayed will only have a OK button. If Title is null, a default title will be chosen depending on the value of Dialog_Type.

This function will return only after the user pressed one of the buttons or deleted the dialog, by running an additional level of main loop. One of the following values will be returned:

- Button_None
- Button_Abort
- Button_Yes
- Button_Ok
- Button_Retry
- Button_No
- Button_Cancel
- Button_Ignore
- Button_All
