Just to add to your confusion, in my machine both commands work all right
(Windows XP, Version 4.1). Sorry.

I'm confused here. If I try the following command
Plot3D[Abs[1+(x+Iy)^3],{x,-1.25,1.25},{y,-1.25,1.25},PlotPoints->40,Mesh->Fa
lse,FaceGrids->All]
I get a nice 3D plot of a surface that has dimples where the complex zeros
are.
BUT
If I try the following:
f[x_,y_]:=Abs[1+(x+Iy)^3]
Plot3D[f[x,y],{x,-1.25,1.25},{y,-1.25,1.25},PlotPoints->40,Mesh->False,FaceG
rids->All]
Mathematica refuses to plot it at all giving me at least half a dozed
incomprehensible error messages. I imagine I'm using some sort of
wrong convention but damned if I can figure it out.
I'm using Mathematica 3.0 on a Mac clone (PowerTower Pro with G3
accelerator) running OS 8.6.
I'd be most grateful for any help.
thanks,
Warrne Rogers
