This command causes an event to occur. For examples, see the
structured system variable ^$WINDOW. Depending on the type

The ability to trigger events that are to be processed by other processes is introduced.
Suppose that the value of local variable X is the process-ID of one process, and that this process is intended to process events that are triggered by another job. Let the value of local variable Y be the process-ID of this other job.
Either process could issue a command like:
When the process identified by Y issues the command
the process identified by X will start executing the routine ^PROGRAM. When the process identified by X started recognition of IPC events with the command ESTART "IPC", this processing will occur synchronously, when the recognition was started with ASTART "IPC", this processing will occur asynchronously.
