How to move the active document? SaveAs does not change ActiveDocument

[kiln]

How does one move the active doc; this issue is givimg all sorts of
problems. I've tried several solutions but not work reliably.

For instance, I thought I'd perform a SaveAs from within Word; that
should move the Active Document pointer or whatever it's called to the
newly saved doc; the orig doc should be closed. Then, use Kill to delete
the orig file. This approach works fine on some machines, on other
machines it fails with error 70 permission denied. The orig file is
still open on some machines (but not others). On those machines I can
see that the file exits in both locations, and the open file is the orig
file.

Why is word so inconsistent with this fundemental behavior? Via menu
choices, in all cases SaveAs moves the current file to the "new" file. I
am programming in Word 2002 and the machines that have this issue are
Word 2000 - but the saveas behavior is so basic that I can't imagine
that it's deliberately different programming this in the two versions.

Frankly programming word is a real pita. Handy when it works but
terrible getting it there.
