The screens used in the applications are referred to as panels. Applications can make use of four general types of panels:
Menu and list panels are defined using the CAS Menu and List maintenance functions and their presentation is controlled by using these facilities.
Data entry panels are defined using MODS Panel Maintenance. A panel definition specifies the input and output fields that appear on a panel (as well as some aspects of their behavior), and controls the appearance of the text on the panel (for example, color and highlighting). These panels are invoked using the &PANEL NCL statement.
Note: For more information, see the Network Control Language Programmer Guide.
Text-entry panels are used to display and maintain freeform text. These panels differ from other panels in that you do not need to provide a panel definition—a standard panel is presented by the CAS text editor facility.
