A menu is a list of options presented on a screen for selection. A menu can be part of an application; it can be a login screen for a group of users or it can be an individualized login screen. Menus are created through the
DEFINE_MENU tool.
There are four different menu styles available to choose from when you are defining a menu. The styles you choose depend on your design requirements and intended use. Some styles require preliminary preparation such as predefined screens and applications, while others can be used directly.
