☜	ETRIGGER M[UMPS] by Example					☞

Introduced in the 1995 ANSI M[UMPS] Windowing Application Programmer’s Interface standard.

This command causes an event to occur. For examples, see the structured system variable ^$Window. Depending on the type of event thst is to occur, the event specification will be in:
^$Window (window,"EVENT",type)
^$Window(window,"G",gadget,"EVENT",type)
^$Window(window,"T",timer,"EVENT",type)
^$Window(window,"M",menu,"CHOICE",item,"EVENT",type)

Approved for addition in a future M[UMPS] Windowing Application Programmer’s Interface standard.

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:
Set ^$Job(X,"EVENT","IPC",Y)="^PROGRAM"

When the process identified by Y issues the command
ETrigger "^$Job(X,""EVENT"",""IPC"",Y)"
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.
