Using EDF with your task-related user exit program
If your exit program sets the EDF bit in the schedule flag word and EDF is active,
the exit program is invoked before and after each API request to format screens for
EDF to display.
Communication between the task-related user exit and EDF is controlled by the
task-related user exit interface. The command flow between this interface, EDF, and
the task-related user exit is summarized in Figure 10 on page 279.
