I would like to define variables numerically as the
solution of equations, and then use these variables with
as little rigamerole as necessary.  

As an example, suppose I have two equations r and rr, and
two variables b and c which occur in them.  Now when I enter

	fsolve({r,rr},{b,c})

it will produce the values of b and c.  What I want done is
to use this, without too much additional syntax, to DEFINE
the values of b and c for subsequent work.

Also, I would like this to undefine previous values.

The only solutions I have found or suggested by Maplesoft
are at best complicated, and I am not even sure they work.

This must be a common problem, present in any iterative
solving scheme of any complexity.
