HyperCard 2.1 doesn't have a built-in command for sending an arbitrary
Apple event, but you can definitely send Apple events from an XCMD.  We'll
release an example of such an XCMD, called SendAppleEvent, to developers.

Technical sidenote:

An XCMD can easily convert the address of a program in HyperTalk (a string
of the form "Zone:Macintosh:Program") into an Apple event address descriptor,
by invoking an Apple event coercion handler that HyperCard installs.

More later.
