screen form

A data entry form displayed in a 4GL window (or the Application window itself) and used to support input or output tasks in a 4GL application. A screen form is defined in a form specification file. Before a 4GL program can use a screen form, this file must first be compiled. The form in the current 4GL window is called the current form. Most user interaction statements use a screen form for their input and output.
