Select the Object / Design function or click on the 
toolbar button to change to design mode, in which you can display the entire object as well as modify it.
Creating a New Object
To create a new object, select the Object / New... menu item. This menu item either branches directly to an empty design window for the object or to a submenu. Thus, for example, for the Table object, you can choose among New / Table, New / Table Like, and New / Table as Query. For a detailed description of how to define a particular object, please refer to the section named after the object.
You can also click on the 
toolbar button. Normally, this corresponds to the Object / New function. If the Object / New function comprises a number of
submenu items, the toolbar button corresponds to the first subfunction (e.g., Object / New / Table for the Table object).
The Object / Copy function provides you with another way to create a new object. Object / Copy copies an existing object to an empty design window. Here you can make any changes you wish before finally creating the object under the desired name.
After you call the Object / Save menu function, an object is not actually created until you have entered the name of the object and have successfully executed the action. In the event of an error, DOMAIN issues a message and does not exit design mode.
If you use the Object / Close function to exit design mode after modifying the object, DOMAIN asks you whether you would like to save the changes.
