OK, great!  Please keep us up to date, and let us know if we can help.  We
are really at the stage of doing major evolutions, and this is our big
bottleneck, as always.  But although we are really making progress in many
ways, I still long for the days of the CM-5 when we able to do big
simulations routinely using CMstab!

	Please stay in touch,
	Ed
