  Here's another Open VMS Alpha AXP internals C question...

  I'm converting some MACRO to C, and am changing  $DEFINI type
blocks of code to  structures...and some of these need locking down, eg. 

	$DEFINI	psb

$DEF	zzz$l_zeep	.blkl	1	
$DEF	zzz$l_zap	.blkl	1
$DEF	zzz$l_zip	.blkl	1
$DEF 	zzz$k_len 

$DEFEND	psb

psbdat:	.blkb	zzz$k_len
range:	.long	zzzdat
	.long	zzzdat + zzz$k_len

	$lkwset_s	inadr = range


  Now, I'm trying to use a structure...

	static struct
		{
		int l_zeep
		int l_zap
		int l_zip
		} zzz ;

  What would be the "best" way to "calculate" the address of the ends of
  structures to place in a range array for calling sys$lkwset?
