@acer hi,

I would like to explain using an example. In Maple, assume that we have a second-degree equation such that f(a, b, c) = a x² + b x + c. When we run Pascal, we transfer a, b and c from Lazarus Pascal to Maple. Once Maple has finished, it will send the roots back to Pascal. If you could write a short code, it would be easier to apply it to my real problem.

Thanks.
