You use forms to layout the pages of SAPscript documents. To process a document for printing, both on the screen or printer, you must assign a form first. Output is not possible without a form.
If a text has no form, the system automatically assigns the form SYSTEM, which contains the minimum of definitions required to process the text for output.
With the graphical layout design, creating and modifying forms becomes much easier. You can use the mouse to intuitively make changes, which you can immediately see on the screen (drag & drop, cut & paste).
