another elementary question

["R Tennenbaum"]

I'm trying to rig a tiny xpl program that involves overwriting the same
file every time it's invoked. It starts with saving defined text to a
filename:

	savedef filename

which I want to be the same every time, but every time it asks me to
confirm whether I want to. Is there a switch to turn off the inquiry?
(savedef /y filename actually completes, but doesn't work.) Or if
there isn't, I've forgotten how to tell the program yes. It's not a va
$er thing, right? No?

I did used to know. Really.
