Hi Audrey,
	If I understand the problem you are having -- accessing
the values of axis variables -- then I think it can be solved by
defining variables that refer to the axes.
	For example, if you are dealing with a gridded variable V
or with a grid named "grd" then define
	let xx=x[g=V] ; let yy=y[g=V]
or
	let xx=x[g=g=grd] ; let yy=y[g=grd]
Now you can use the syntax `xx` to get at the appropriate axis value.

Hope that helps,
Mick
