If this is the first time you start Eclipse, you now see the Eclipse Welcome page which you can close.
By default, the IDE should start in the COBOL perspective indicated by the button in the right upper corner of the IDE. Perspectives are Eclipse concept and they include the views, menus and options relevant to your activity. The COBOL perspective shows the COBOL Explorer, Outline and Console views, among others. The perspective is customizable, so you can choose your own views.
The COBOL Project wizard is displayed.
