I'm trying to write a macro in this much-touted macro language.  Most things
are fine, and I can use the recorder for lots of stuff, but I've bumped into
something I can't quite figure out.

I have some data that I want to chart.  Every week I add a new data point.
I have arranged the stuff so that making the chart is easy.  I have a name
for the last point, and I have the macro go there and fool around to create
the new data point using relative motion.  Now I want to create the chart
afresh, and I cannot for the life of me figure out how to select the new
larger chart region.
	a) If I record what happens when I select the old chart and type
	   shift-downarrow, I get =select(some absolute stuff), which
	   does me no good.  The form of the absolute stuff depends on
	   whether references are absolute or not, but it's still fixed.
	b) I have not found an acceptable syntax to the select function
	   which mixes the current point and a named point (I could do that)
	   or two named points (I could do that too) though I tried harder
	   on the first.

I know that what I want to do is add a row to the range I had before.  I can
name the range or any of its corners easily enough because it's just two
columns and I have to know the top and bottom anyway.

It seems this should be easy, but it's not.

Help, please, anyone who has hacked the macro language already!!
