How does UpdateSource change a non-opened document?

[Larry]

From the nature of Word, and the nature of all computer files, it would
seem to be impossible for a change to be made and saved in a
_non-opened_ document. Yet that is what is done by the UpdateSource
command. If I have bookmarked text in Word Document X, and an
IncludeText field in Word Document Y which displays that bookmarked text
from Document X, and I change the text in the field in Document Y and
run the UpdateSource command, when I next open Document X it will
_already_ reflect the change that was made in Document Y.

This is a great feature, but I don't see how it's possible. My gosh,
even to print a document (without changing anything in the document),
Windows must open the document for a moment. Yet the UpdateSource
command is making substantive changes in a document without opening the
document at all. The fact that it's not opened is shown by the fact
that following running UpdateSource in Document Y, Document X does not
appear in the Recently Used File list in Word.

You have already answered your own question.
The Word command IncludeText links Doc X
with Doc Y. You alter Doc Y and issue the
special command UpdateSource, which orders
a change in data in Doc X. It does not display
Doc X in Word (because that is done by a
separate command, Open File.)

I know that the document is changed without being opened. I was
wondering _how_ this is possible.

the linked file is already open, as soon as any other linked file is opened,
the file is not open in the viewing pane, it is done in the background, as
much in windows is.

You've just repeated my question back to me. I know that the document
is changed without being opened. I was wondering how this is possible.

Do a Google search for OLE (or "Object Linking and Embedding") and the
answer should become clear.
