SCREEN versus LAYOUT section

To design a form with IBM® Informix® 4GL, you organize labels and fields in the SCREEN section of a .per form file. Genero Business Development Language introduced a new LAYOUT section to place form elements. The new LAYOUT section allows more sophisticated form design than SCREEN.

When writing new programs for GUI applications, it is recommended that you use a LAYOUT section instead of SCREEN. However, the SCREEN section is still supported to be used to design TUI mode forms.
