Function Key Areas

The function key area (FKA) refers to the bottom two lines of a panel, where function keys and their labels are displayed.

You can modify the labels and actions associated with function keys through the CAS API.

CAS provides predefined function key sets for specific purposes, such as Browse and Update.

The FKA lines are formatted and returned to the calling procedure either when the CAS API is invoked to set key settings or when the KEYS command is executed by the user.
