You may find one of the free Scheme implementations more useful
for your prototyping work.  An older version of ELK Scheme
(very good) is available from comp.sources.misc.

I'm using Scheme (mini LISP) as the base for my work and it's
very nice.  The code-as-data functional programming approach
is very handy for what you describe.

There is, in fact, a Macsyma/mathematica-type symbolic algebra
manipulator available for Scheme.  You might be able to use
it as a subroutine in your stuff.  It's called Jacal, and it's
written by the author of another fine Scheme implementation called
SCM.
