This warning appears when you use the 4GL forms compiler to compile a multipage PERFORM screen. A 4GL program can display only the first page of a multipage form. If the form specification has more than one SCREEN section, it has been purposely divided into multiple pages, and you will have redesign it for 4GL. If it has only a single screen layout, the 4GL forms compiler has split it into two pages because it will not fit on the screen. The form design might not allow for the four screen lines that 4GL reserves.
