Forms in pop-up display style can be displayed without removing previously displayed forms from the window. A pop-up style form temporarily covers over some or all of the previous form. Thus, by using pop-up style forms you can have multiple forms, or portions of forms, visible at the same time. The cursor is only active in one form at a time—always the last form activated.

You can make pop-ups any size up to the size of your window, but they are most useful when you make them small enough to be displayed without completely obscuring previous forms. When specifying the size of a pop-up form, allow space for a border, if you choose to use one. For more information, see Form Size and Position.

You can specify that a pop-up style form appear at a specific window location or automatically float to a position near to but not obscuring the field in the previous form that contains the cursor.

Pop-up style forms can be used for a wide variety of purposes:

When using pop-up forms in an application, the application code controls the appearance and disappearance of the pop-up. When your application code displays a normal fullscreen form, it clears the previous form from the screen. When your application code displays a pop-up form, the previous form remains in your window.
