@Preben Alsholm That looks a lot better.  I though I had tried something similiar with complex numbers and dsolve and was getting weird errors.  It's really slow right now with the actual function (derivate of the log of the composition of 20 complex maps) but it got a bit convoluted trying to work around the real to complex issues.

Thanks.

Entering this exactly gives "Non-fatal error while reading data from kernel." after the 'curve:=dsolve.." line.

But then it works!  Thanks!

I still can't see how the 0. I is sneaking out of F1 though.

And, parameters aren't supported in Maple 16 either: "Error, (in dsolve/numeric) problems with parameters cannot be specified via procedures"

Thanks again.

The loop version is just what I needed.  Thanks.

I failed to mention it, but the reason for the intermediate step instead of just using DEplot was to apply a conformal map to the resulting curve before plotting.  So for the one-off graph I need, the element at a time list construction is easier to work with, though slower.
