Has anyone had experience with filling XAB's?  Specifically, I'm having
trouble with the XABSUM block, which is supposed to give the number of
areas & number of keys that a file has.  Unfortunately, for any file
I open, regardless of whether it is indexed or not, my XABSUM block always
seems to show zero areas and zero keys.  A code sample follows.
--------------------------
    	.title	x
    	.psect	x_data,wrt,noexe,noshr
fab:	$fab	xab=xabsum,fac=<bio,get>,shr=upi,fnm=<INPUT:>
xabsum:	$xabsum
    	.psect	x_code,nowrt,exe,shr
    	.entry	x,^m<>
    	$open	fab=fab
; look at contents of xabsum block at this point
    	$close	fab=fab
    	movl	#1,r0
    	ret
    	.end	x
--------------------------
I'd appreciate any clues someone might give.
