 Hi,
 	
         I am interested in Mma routines that solve complex ODE's. Is there
 any at all? Another programs are welcome too.

	My interest is in the following kind of system of ODE's:

		dY/dT = p(X,Y)
        	dX/dT = q(X,Y)

where X and Y are functions of T (T is COMPLEX), p and q are, say, complex
polynomials. I want to solve it NUMERICALLY. For it, is necessary to specify
a path through that the solution will be computed, since we are working in
complex plane. 
	I have a program, written in FORTRAN (in 1985) that works, but
I don't have access to the program sources and I wish to work with a more 
sophisticated environment. 
	Any help will be appreciated.
	Regards,

						Nivaldo.
