I'm not sure I want to insert a message handler in the normal message
passing hierarchy. I don't want it to ever be called automatically. I
want to be able to call a handler manually, from another handler. At
the moment, unless the two handlers are in the same "file", I can't call
it because I can't "see" it. I just want to be able to declare a
handler that can be invoked manually from anywhere in the program. This
is a visibility issue.
I hope I'm making this clear[er].

You raise an important issue. To program effectively in Revolution,
you really need to understand the message-passing hierarchy. Nobody
has explained it better than Richard Gaskin at:

There is no concept of global handlers. If you want a handler to be
accessible to all the message handlers in a given stack file, just
put it in the mainstack. If you want it available across multiple
stack files, you'll need to create it as its own mainstack and then
include it by making it a library with "start using."

I want to write some utility routines that can be used by lots of
message handlers. Where do I put those utility routines so that the
event handlers can "see" the utility routines? Do I have to declare
them as Global, or just put them in a particular place?
Thanks!
