Post Invocation
Post Invocation event points execute once for a parent process, immediately after a child completes execution. The predefined field OPTION can be interrogated to determine if the child ended normally or was cancelled.
The predefined field INCLUDE CHILDREN can be used to control whether or not one or more child processes execute. To skip execution, INCLUDE CHILDREN must be set to 0 or N (no). Its effect depends on the event point it is set in, as follows:
If set to 0 or N in End of Frame, all child processes are skipped. (Recall that End of Frame executes before any children are invoked.)
If set to 0 or N in Pre-Invocation, that single child process is skipped.
If set to 0 or N in Post Invocation, all remaining child processes are skipped.
