Using Errorf in IDL [message #8963]

I recently tried to feed a complex argument to Errorf, but it would have
none of it. With Mathematica you get a complex numerical result
if you feed Erf a complex numerical argument. I assume Mathematica is
calculating the principal value of the integral or something like
that. So my basic question is, how can I do the same thing most
efficiently in IDL? (If I have to I can numerically integrate
Fresnel integral euivalents or something else equally disgusting
but I'm praying for something simple) Perhaps just as useful
would be if somebody could give me a form for A(a,b),B(a,b) in:

A + iB = Erf(a + ib)

Thanks for any tips,
