Thanks for the detailed reply. I think that, as a general rule,
it would be good to take the C filters by Andrey Grozin as a model
for writing the interfaces with extern systems. Even though this
may necessitate to write a few routines for string substitutions
yourself, his approach has the advantage of being very portable,
because it only relies on standard ansi C without special libraries.

As to the improvement of the maple interface, I think that we would
all be delighted to have something which works everywhere,
and for all versions of maple... Did you get any news from
the Maple developers of how to replace the output routines?

Best wishes, Joris
