LEAVE LIST-PROCESSING
Other versions: 7.31 | 7.40 | 7.54
Syntax
LEAVE LIST-PROCESSING.
Effect
This statement immediately exits the list processor. The runtime environment continues the processing with the
PBO event of the screen from which
the list processor was called using LEAVE
TO LIST-PROCESSING or the screen that was set using the AND RETURN TO SCREEN addition to this statement.
If the statement is not executed when the list is displayed by the list processor, it has no effect, except in the event blocks for
reporting events. Here
it branches to the end of the program and processing continues as described for the SUBMIT statement.
When the list processor is exited, the list buffer of the screen sequence is initialized. New output statements describe a new basic list.
Example
This example shows the recommended procedure for displaying lists during screen sequences. A separate screen 500 is defined for calling the list processor. The
screen does not contain any screen elements and it calls a single PBO module call_list but no
PAI modules. The entire basic list,
including the GUI status, is defined in the PBO module. When the screen is exited using LEAVE
SCREEN, its processing is stopped and the list processor is started. The list events are handled in the same program. When the list processor is exited the screen sequence of screen 500 is ended, because the
next screen 0 is specified when the list processor is called.
