How can a page know which frame in a frameset it is in?

window.name
gives you the name of the window or frame thus whatever.html when loaded in
<frame name="frameName" src="whatever.html">
can check
if (window.name == 'frameName')
That obviously does not help with unnamed frames but then you would need
to walk the frames and compare each to window to find out which frame
you are in.

re: What frame a page is in

You did not say where your script is: in the frameset or in an inner
frame.
For inner frames could be:

function whereIAm() {
var tmp = null;
for (i=0;i<window.top.frames.length;i++) {
if (window.top.frames[i] === self) {
tmp = window.top.frames[i];
break;
}
}
return tmp;
}

If you are using nested framesets (I hope not :-), then you need to use
recursive calls checking if (window.top.frames[i].frames) != 0

If the frames are unnamed and I do a comparison, say,
window.frames[1].location == self.location
that would "fail" if the same page was loaded into more than one frame.

So does that mean that in some situations the page can't know what frame
it's in?

There is no need to compare the location, you should compare the objects
e.g.
parent.frames[1] == window
